Kacy Byxbee is best known as the longtime partner of Scott Caan, the actor famous for playing Danny “Danno” Williams on Hawaii Five-0. But Kacy was not simply visiting the set as an actor’s girlfriend. She had her own behind-the-scenes career in costume and wardrobe, including extensive work on the same television series.
Their connection eventually developed into a long-term relationship, and in July 2014 they welcomed their daughter, Josie James Caan. Entertainment coverage at the time described Kacy and Scott as a very private couple who had already been together for several years.
That privacy has continued to shape Kacy’s story. There is reliable information about her wardrobe work, her relationship with Scott, and their daughter, but considerably less trustworthy information about her childhood, parents, education, age, and personal finances. Instead of filling those gaps with guesses, her confirmed story gives us a more interesting look at someone who worked inside Hollywood without trying to become a Hollywood celebrity.
Who Is Kacy Byxbee?
Kacy Byxbee is an American costume and wardrobe professional who has worked in film and television.
IMDb credits her in the costume and wardrobe departments of Somewhere, Hawaii Five-0, and All at Once.
She became more widely known after beginning a relationship with Scott Caan.
Scott is the son of legendary actor James Caan, but he established a substantial acting career of his own through movies such as Ocean’s Eleven and television series including Hawaii Five-0.
Kacy, meanwhile, remained primarily behind the camera.
That difference appears to suit her.
While Scott has spent decades acting in front of millions of viewers, Kacy has rarely given major interviews or turned their relationship into a public brand.
When Was Kacy Byxbee Born?
Kacy’s exact birth year is not firmly established by authoritative public records.
Some online profiles list her birthday as January 24, but reliable mainstream reporting does not consistently provide a year of birth.
Because of that, claims online giving a precise age should be treated cautiously.
There is also limited verified information about her birthplace, parents, siblings, or childhood.
This is an important point because Kacy has become the subject of many biography pages since her relationship with Scott became public.
When information is missing, some sites simply repeat claims from other sites.
That does not make those claims verified.
What Does Kacy Byxbee Do for a Living?
Kacy has worked professionally in costume and wardrobe departments.
This is one of the strongest documented parts of her biography.
Her credits show that she worked as a costume staff assistant on Sofia Coppola’s 2010 film Somewhere. Metacritic’s production credits independently list Kacy Byxbee in that role.
She then worked extensively on Hawaii Five-0.
IMDb credits Kacy with costume-department work on 69 episodes of the series between 2011 and 2014.
She later received a wardrobe credit on the 2016 movie All at Once.
These credits show that Kacy had genuine production experience rather than simply being connected to the industry through Scott.
What Does a Costume and Wardrobe Professional Actually Do?
Costume work is easy for audiences to overlook.
Actors appear on screen wearing clothing that looks natural for their characters, so viewers may never think about the work behind it.
But wardrobe departments can be responsible for organizing clothing, maintaining continuity, preparing outfits, making sure costumes are available when needed, and helping execute the costume designer’s larger vision.
On a long-running television show such as Hawaii Five-0, continuity becomes particularly important.
Characters may appear in multiple scenes filmed on different days.
Clothing needs to remain consistent with the story.
Wardrobe teams therefore form an important part of television production.
Kacy spent years working inside that environment.
Did Kacy Byxbee Work in Theater Too?
Yes, there is evidence of theater costume work.
The published script and production record for Scott Caan’s play No Way Around But Through lists Kacy Byxbee as the costume associate for its 2012 world premiere at the Falcon Theatre in Burbank, California.
Scott starred in the production alongside Melanie Griffith, Robyn Cohen, Bre Blair, and Val Lauren.
That credit adds another piece to Kacy’s professional history.
Her work was not limited to television.
She had experience across film, television, and live theater.
How Did Kacy Byxbee Meet Scott Caan?
Entertainment reporting says Kacy and Scott met while working on Hawaii Five-0.
The connection makes sense.
Scott starred as Detective Danny “Danno” Williams.
Kacy worked in the costume department.
They were therefore part of the same production environment for years.
The series began in 2010, while Kacy’s documented costume work on it runs from 2011 through 2014.
By 2013, Scott was publicly talking about having a girlfriend.
He did not reveal many details, which became typical of how the couple handled their relationship.
What Did Scott Caan Say About Kacy?
Scott gave fans a rare glimpse of their relationship during a 2013 appearance on Chelsea Lately.
Talking about his girlfriend, he joked that she deserved a “purple heart” because he considered himself a complete disaster.
It was a funny comment, but it also showed something important.
Scott was acknowledging that he was in a serious live-in relationship without turning Kacy into a constant topic for entertainment media.
That balance continued after they became parents.
The couple did not formally announce Kacy’s pregnancy themselves, according to E! News.
They simply continued living relatively privately.
When Did Kacy Byxbee and Scott Caan Start Dating?
There is no firmly documented first-date anniversary.
However, when E! News reported the birth of their daughter in July 2014, it described Scott and Kacy as having dated for at least several years.
Their relationship therefore appears to have begun during the early years of Hawaii Five-0.
That would make their relationship more than a decade old today.
Rather than relying on a specific unverified dating anniversary, the safest conclusion is that Kacy and Scott became a couple in the early 2010s after connecting through the show.
Is Kacy Byxbee Scott Caan’s Wife?
This is where online information becomes complicated.
Older and highly reliable entertainment reporting consistently described Kacy as Scott’s girlfriend or longtime partner. E! News used that description when their daughter was born in 2014, and IMDb’s Kacy Byxbee biography still describes Scott as her boyfriend.
However, Scott’s current Wikipedia profile lists Kacy Byxbee in the spouse field.
The problem is that there has not been a widely reported public wedding with a clearly documented date.
For that reason, describing Kacy as Scott Caan’s longtime partner is currently the most cautious wording unless stronger marriage documentation becomes public.
What is not in doubt is that they have shared a long relationship and have a daughter together.
When Did Kacy Byxbee Become a Mother?
Kacy and Scott welcomed their daughter on July 9, 2014.
Her name is Josie James Caan.
E! News confirmed the birth later that month and reported that Josie was the couple’s first child.
The pregnancy itself was handled privately.
There was no huge celebrity announcement or carefully planned magazine reveal.
That approach was consistent with Kacy and Scott’s relationship as a whole.
They allowed the public to know basic information without making their family life a constant source of publicity.
Who Is Josie James Caan?
Josie James Caan is Kacy Byxbee and Scott Caan’s daughter.
She was born July 9, 2014.
Her middle name immediately attracted attention because Scott’s father was legendary actor James Caan.
People has also noted Scott’s tribute to his father through his daughter’s name.
That gives Josie an interesting connection to Hollywood history.
Her father is an actor.
Her grandfather was one of the defining American film stars of his generation.
Her mother worked behind the scenes in film and television.
Yet Kacy and Scott have largely protected Josie from unnecessary publicity.
A natural internal-link opportunity would be James Caan’s five children and the Hollywood family he left behind.
Was James Caan Kacy Byxbee’s Father-in-Law?
James Caan was Scott’s father and therefore Josie’s paternal grandfather.
Whether “father-in-law” is technically appropriate depends on Kacy and Scott’s legal marital status, which has not been consistently documented publicly.
The family connection itself is clear.
James Caan became famous through films including The Godfather, where he played Sonny Corleone.
He had five children from four marriages, with Scott born during his marriage to actress and model Sheila Ryan.
James died in July 2022 at age 82.
His death left Scott as one of the most recognizable members of the next generation of the Caan family.
Who Is Scott Caan?
Scott Caan was born on August 23, 1976, in Los Angeles, California.
His parents were James Caan and Sheila Marie Ryan.
Scott did not begin his creative career solely as an actor.
During the 1990s, he was involved in hip-hop and performed under the name Mad Skillz as part of the Whooliganz alongside the musician who later became famous as The Alchemist.
Acting eventually became his primary career.
He appeared in Varsity Blues, Gone in 60 Seconds, and the Ocean’s trilogy.
Then came Hawaii Five-0.
Scott played Danny Williams throughout the show’s 2010–2020 run and received a Golden Globe nomination for the role.
That same show also brought Kacy into his life.
A useful internal-link opportunity would be Scott Caan’s career from The Whooliganz and Ocean’s Eleven to Hawaii Five-0.
How Did Hawaii Five-0 Change Kacy’s Life?
Professionally, it gave Kacy one of her largest documented wardrobe credits.
Personally, it appears to have introduced her to the man who became her longtime partner.
IMDb credits her on 69 episodes between 2011 and 2014.
That is significant.
Working dozens of episodes on a television production is very different from receiving one small movie credit.
A television crew can spend months together each year.
The schedule is demanding.
Relationships naturally develop between people working closely for long periods.
For Kacy and Scott, that professional environment eventually became the beginning of a family.
Did Kacy Stop Working After Having Josie?
Her IMDb credits show Hawaii Five-0 costume work through 2014, the same year Josie was born.
She later returned to a documented wardrobe credit on the 2016 movie All at Once.
Beyond that, her public production résumé becomes much quieter.
That does not prove she permanently left costume work.
Film databases only show credited work and do not necessarily capture every private or uncredited professional activity.
The responsible wording is that her publicly documented costume and wardrobe credits became less frequent after the mid-2010s.
Is Kacy Byxbee a Model?
Many online biographies describe Kacy as a model.
Famous Birthdays, for example, labels her as a model while also noting her costume work.
However, her strongest verifiable professional record is in costume and wardrobe production.
There is much clearer documentation of her work on Somewhere, Hawaii Five-0, All at Once, and No Way Around But Through than of a substantial professional modeling career.
So calling her a costume and wardrobe professional is more firmly supported than defining her primarily as a model.
Is Kacy Byxbee a Journalist?
Some newer biography websites describe Kacy as a journalist or writer.
Reliable entertainment-industry records do not provide enough evidence to establish journalism as a major part of her professional career.
Her documented production credits are much clearer.
This is another example of why celebrity biographies need careful checking.
Once one website attaches an occupation to someone, dozens of others may repeat it.
Repetition is not the same as verification.
Does Kacy Attend Red-Carpet Events?
Yes, although selectively.
Kacy has occasionally appeared publicly beside Scott.
Famous Birthdays notes that the couple attended a screening of Untogether at the Tribeca Film Festival in 2018 and appeared at the Entourage premiere in California in 2015.
These appearances show that Kacy does not completely avoid Hollywood events.
She simply does not appear interested in building her own celebrity identity around them.
There is a difference between supporting a partner publicly and seeking constant publicity.
Kacy seems much closer to the first category.
Why Is Kacy Byxbee So Private?
Kacy has not given a major interview laying out a formal reason for her privacy.
But Scott is also known for keeping much of his personal life away from public attention.
Even their pregnancy was not formally announced by the couple before entertainment outlets reported it.
Their daughter has similarly been kept away from constant publicity.
This makes Kacy somewhat unusual in modern celebrity culture.
She has enough connection to Hollywood to attract attention.
She has professional credits of her own.
Her partner comes from a famous acting family.
Yet she has never turned those connections into a highly public lifestyle brand.
How Is Kacy Different From Many Celebrity Partners?
The biggest difference is that she already understood film production from the inside.
Kacy was not simply introduced to movie sets because she began dating an actor.
She worked on those sets.
Her job required understanding schedules, costumes, continuity, and the less glamorous daily work behind television production.
That probably gave her a very different view of Scott’s career.
She knew that making television was not simply premieres and interviews.
It involved early mornings, long shooting days, wardrobe changes, production problems, and months of work.
Their relationship therefore grew from a shared professional environment rather than from celebrity social circles alone.
Does Kacy Byxbee Have More Than One Child?
The strongest established sources identify Josie James Caan as Kacy and Scott’s child.
Some newer online biographies claim the couple later welcomed another child, sometimes giving 2022 as the year. However, that information is not consistently supported by established entertainment reporting or Scott’s current IMDb biography, which lists Josie as his child.
For that reason, it would be premature to present a second child as firmly verified.
Based on the strongest publicly available evidence, Josie is the couple’s confirmed child.
Is Kacy Byxbee Still With Scott Caan in 2026?
There is no credible current report of a breakup.
Current biographical records continue to connect Kacy and Scott, although sources differ over whether to call her his partner or spouse.
Because both have kept their relationship private, there are fewer public updates than fans might expect from a couple connected with Hollywood.
A lack of social-media posts does not itself prove anything about a private relationship.
The most careful conclusion in 2026 is that Kacy remains publicly identified as Scott Caan’s longtime partner, with no reliable report establishing a separation.
What Is Kacy Byxbee’s Net Worth?
Kacy Byxbee’s personal net worth has not been reliably verified.
Many celebrity websites attach exact amounts to her.
Those figures usually lack supporting financial documents.
Kacy has earned income through professional costume and wardrobe work, while Scott has enjoyed a long acting career.
But Scott’s earnings cannot simply be counted as Kacy’s personal wealth.
Without verified information about her salary, investments, property, business ownership, or other assets, an exact net-worth figure would be speculation.
What Is Kacy Byxbee Doing Now?
Kacy remains largely private in 2026.
Her publicly documented entertainment credits are concentrated mainly between 2010 and 2016.
There is no strong evidence of a major current film or television project under her name.
That does not necessarily mean she no longer works.
It means her current professional activity is not extensively documented in public entertainment databases.
Her family life with Scott and Josie also remains largely outside public view.
For someone connected with one of Hollywood’s best-known acting families, that is a remarkable level of privacy.
Interesting Facts About Kacy Byxbee
Kacy has genuine behind-the-scenes Hollywood experience rather than being known only because of Scott Caan. She worked as a costume staff assistant on Sofia Coppola’s Somewhere and later spent 69 episodes in the costume department of Hawaii Five-0.
She also served as costume associate for the 2012 premiere of Scott Caan’s stage play No Way Around But Through.
Kacy and Scott reportedly met through Hawaii Five-0 and had already been dating for several years when their daughter was born.
Their daughter, Josie James Caan, was born on July 9, 2014.
Josie’s middle name connects her with her famous grandfather, James Caan.
Kacy occasionally attends public events with Scott but has never developed a heavily public celebrity persona.
Her exact birth year, education, parents, personal net worth, and current professional projects remain largely private.
Final Thoughts
Kacy Byxbee is often introduced as Scott Caan’s partner.
That is understandable.
Scott starred in Ocean’s Eleven and spent a decade playing one of the main characters on Hawaii Five-0.
His father was James Caan, the legendary actor behind Sonny Corleone in The Godfather.
But Kacy’s story did not begin with celebrity dating.
She was already working behind the scenes.
In 2010, she worked in the costume department on Sofia Coppola’s Somewhere.
Then she joined Hawaii Five-0.
Over several seasons, IMDb credits her with work across 69 episodes.
Scott happened to be one of the show’s stars.
Their professional worlds crossed, and eventually the relationship became personal.
By 2013, Scott was publicly joking about his girlfriend.
Then, on July 9, 2014, Kacy gave birth to their daughter, Josie James Caan.
Even that major event did not transform them into an intensely public celebrity couple.
They kept their relationship quiet.
They protected their daughter.
And Kacy continued avoiding the type of constant exposure that often follows someone connected to a famous family.
There are still questions about her.
Her exact age is unclear.
Her early family history is private.
Her current work is not heavily documented.
Even her exact marital status with Scott is described differently by different current sources.
Those gaps do not need to be filled with invented details.
What is confirmed already gives Kacy a clear identity.
She is a costume and wardrobe professional who worked on major productions.
She spent years behind the scenes of the television show that made her partner especially famous.
She became the mother of Josie James Caan.
And she built a long relationship with Scott while largely refusing to turn their family into entertainment for the public.
In a family where the Caan name has been famous for generations, Kacy Byxbee has taken a noticeably different path.
She has stayed close to Hollywood while remaining mostly outside its spotlight.
