Kacy Byxbee is a costume and wardrobe professional best known publicly as the longtime partner of Hawaii Five-0 actor Scott Caan. She has her own behind-the-scenes entertainment career, with credits on Somewhere, Hawaii Five-0 and All at Once, which can be seen on Kacy Byxbee’s IMDb profile. Kacy and Scott reportedly met while working on Hawaii Five-0, later became a couple and welcomed their daughter Josie James Caan on July 9, 2014.

Who Is Kacy Byxbee?
Kacy Byxbee is sometimes described online simply as “Scott Caan’s girlfriend.”
That description is incomplete.
Long before most people searched her name because of Scott, Kacy was working behind the scenes in television and film.
Her professional work was in costume and wardrobe departments.
That means she was part of the team responsible for helping actors look right for every scene.
Costume work can involve much more than choosing attractive clothes.
Wardrobe teams may need to:
prepare costumes,
keep track of multiple versions of an outfit,
make sure clothing matches between scenes,
organize fittings,
handle repairs,
and work closely with actors and costume designers.
Kacy spent several years doing exactly this kind of work on a major network television series.
Kacy Byxbee’s Career Before Fame
One of Kacy’s earliest documented credits is Sofia Coppola’s 2010 film Somewhere.
IMDb lists her in the costume and wardrobe department for the movie.
The film starred Stephen Dorff and Elle Fanning and followed the life of a Hollywood actor staying at the Chateau Marmont.
Kacy was not acting in the movie.
Her role was behind the camera.
This distinction is important because many online profiles incorrectly call Kacy an actress.
There is no established acting filmography attached to her name.
Her documented professional work is primarily in wardrobe.
Kacy Byxbee and Hawaii Five-0
The most important project in Kacy’s career was CBS’s Hawaii Five-0.
IMDb credits her with costume-department work on 69 episodes from 2011 through 2014.
That is not a tiny one-day television job.
Working on dozens of episodes means she was part of the production over several seasons.
Hawaii Five-0 was filmed largely in Hawaii and featured a large cast, action sequences, police uniforms, formal clothes, casual island clothing and many different guest characters.
Wardrobe continuity on a show like that requires careful organization.
It was also on this production that Kacy’s personal life became connected with Scott Caan.
Who Is Scott Caan?
Scott Caan was born on August 23, 1976, in Los Angeles.
He is the son of legendary actor James Caan and actress and model Sheila Ryan.
Scott built his own acting career rather than simply living on his father’s name.
His best-known roles include:
Turk Malloy in Ocean’s Eleven,
Turk in Ocean’s Twelve and Ocean’s Thirteen,
Scott Lavin in Entourage,
and Detective Danny “Danno” Williams in Hawaii Five-0.
He also works as a writer, photographer and director.
His role as Danno lasted throughout Hawaii Five-0’s long CBS run and earned him a Golden Globe nomination.
How Did Kacy Byxbee Meet Scott Caan?
The couple reportedly met on the set of Hawaii Five-0.
That story makes sense because Scott was one of the show’s main actors while Kacy was working in its costume department.
E! News reported in 2014 that Kacy and Scott had been dating for at least several years after meeting on the set.
The exact date when their friendship became romantic is not publicly confirmed.
Some websites say 2010.
Others use 2011.
There is no need to force an exact month or day when the stronger sources simply establish that their relationship developed during the Hawaii Five-0 period.
Scott Publicly Talked About Kacy in 2013
By early 2013, their relationship was publicly known.
During an appearance on Chelsea Lately, Scott joked about how patient Kacy was with him.
He said his girlfriend deserved a “purple heart” because he considered himself difficult to live with.
Us Weekly later recalled the comment while reporting Kacy’s pregnancy.
Scott also discussed how they lived together in Hawaii while he worked on the CBS show.
That gives us one of the clearest early public confirmations of their relationship.
Are Kacy Byxbee and Scott Caan Married?
This is one of the most confusing questions about Kacy.
Some newer websites call her Scott Caan’s wife.
Wikipedia currently labels Kacy as his spouse.
But other stronger entertainment records continue describing her as his partner or girlfriend.
IMDb says Kacy “has been in a relationship with Scott Caan.”
A television profile published around Scott’s 2023 series Alert: Missing Persons Unit also called Kacy his partner rather than wife.
No dependable public wedding announcement, wedding date or marriage record has become a major part of their public story.
Therefore, the safest wording in 2026 is:
Kacy Byxbee is Scott Caan’s longtime partner. Their exact legal marital status is not clearly documented in authoritative public sources.
Kacy and Scott’s Daughter Josie James Caan
Kacy became a mother in 2014.
She and Scott welcomed a daughter named:
Josie James Caan
on July 9, 2014.
E! News reported the birth later that month, calling Josie the couple’s first child.
IMDb confirms the same name and birthday.
Josie is now around 12 years old in 2026.
Because she is still a minor, details about her school, location and everyday routine should remain private.
Why Is Their Daughter Named Josie James?
The middle name immediately attracted attention.
Scott’s father was actor James Caan.
The elder Caan became one of Hollywood’s most respected actors through films including The Godfather, Misery, Thief and Brian’s Song.
People’s recent profile of James Caan’s children also noted that Scott honored his father through his daughter’s name, Josie James.
James Caan died in July 2022 at age 82.
That makes Josie part of a three-generation Hollywood family even though Kacy and Scott have avoided turning her into a child celebrity.
Did Kacy Byxbee and Scott Caan Have a Second Child?
Some newer biography websites claim Kacy and Scott quietly welcomed another child around 2022.
This claim should be handled carefully.
The more established public sources reviewed here continue clearly documenting one daughter, Josie.
IMDb lists Josie as Scott’s child.
A 2023 television profile similarly stated that Scott and Kacy had an eight-year-old daughter named Josie.
There may be newer private family information that has not been publicly announced, but the supposed second child is not established strongly enough to present as confirmed fact.
So the safest answer is:
One child, Josie James Caan, is firmly confirmed. Claims of a second child remain insufficiently verified.
Kacy Byxbee’s Relationship With James Caan
Kacy became connected with one of Hollywood’s most recognizable families through Scott.
James Caan had five children:
Tara,
Scott,
Alexander,
James Jr.,
and Jacob.
Scott was his second child and only child with Sheila Ryan.
When Kacy became pregnant in 2014, Us Weekly reported that James was excited about becoming a grandfather through Scott.
Josie’s arrival gave James another important family connection during the later years of his life.
Kacy Byxbee at Hollywood Events
Kacy is private, but she has appeared publicly with Scott.
One major appearance came at the Entourage movie premiere in Los Angeles on June 1, 2015.
Getty Images photographed Scott and Kacy together on the red carpet.
Later that year, they attended the New York premiere of Rock the Kasbah.
Again, Kacy appeared beside Scott rather than turning the event into publicity for herself.
She also attended a screening of Untogether during the Tribeca Film Festival in 2018, according to public event records.
These appearances show that Kacy has never completely hidden from Hollywood.
She simply does not seem interested in becoming a celebrity personality.
Is Kacy Byxbee a Model?
Some websites describe Kacy as a model.
Famous Birthdays, for example, uses that label.
However, her strongest documented professional credits are in costume and wardrobe work, not modeling.
There is no major agency profile or extensive modeling portfolio consistently cited in stronger entertainment-industry sources.
Therefore, it is more accurate to introduce her as a costume and wardrobe professional.
Modeling may have been part of her background, but it is not as well documented as her production work.
Is Kacy Byxbee a Costume Designer?
People often use “costume designer” broadly when writing about Kacy.
Technically, IMDb categorizes her under Costume and Wardrobe Department.
That does not automatically mean she was the head costume designer responsible for creating the entire visual wardrobe of a production.
For Hawaii Five-0, she is credited as a costumer.
For Somewhere, she worked as a costume staff assistant.
For All at Once, IMDb lists wardrobe work.
So “wardrobe and costume professional” is the most accurate general description.
Kacy Byxbee and All at Once
Kacy’s later documented film credit includes All at Once, released in 2016.
IMDb lists her in the wardrobe department.
This is useful because it shows that her career did not simply disappear immediately after becoming a mother.
However, her public filmography becomes much quieter after this period.
There are no clearly documented major recent productions under her name in the accessible industry records.
What Is Kacy Byxbee Doing in 2026?
This is not publicly clear.
Her strongest professional credits remain:
Somewhere,
Hawaii Five-0,
and All at Once.
Some websites claim she became:
a writer,
editor,
business owner,
fashion entrepreneur,
or lifestyle blogger.
Those claims are much harder to confirm.
There is no reason to assume Kacy stopped working simply because new credits are not publicly visible.
But there is also no reason to invent a current job.
The accurate answer is:
Kacy Byxbee’s current professional activities in 2026 are largely private.
How Old Is Kacy Byxbee?
Her exact age is not reliably established.
Famous Birthdays lists her birthday as January 24, but does not provide a birth year.
Many lower-authority websites assign a year.
The years are inconsistent.
Without a dependable primary or authoritative biographical record, we cannot safely calculate her exact age in 2026.
So articles saying “Kacy Byxbee is exactly 46” or another precise age should be treated cautiously.
The best answer is:
Her birthday is commonly reported as January 24, but her birth year and exact age remain unconfirmed.
Where Was Kacy Byxbee Born?
Famous Birthdays gives the United States as her birthplace.
However, stronger entertainment databases do not provide a detailed birthplace.
Some websites claim Hawaii.
Others name California.
Still others provide different places.
Those contradictions make the precise location uncertain.
It is safer to say she is widely described as American while leaving her exact birthplace open unless stronger documentation emerges.
Who Are Kacy Byxbee’s Parents?
Her parents are not publicly documented by strong sources.
The same is true of most of her childhood.
When Us Weekly reported Kacy’s baby shower in 2014, it mentioned that family, friends and her sisters attended.
That confirms she has sisters.
But their names and private lives do not need to be published unless they themselves become public figures.
Kacy has never presented her family background as a public celebrity story.
Kacy Byxbee’s Education
No dependable source clearly establishes where Kacy went to:
high school,
college,
or university.
Several biography websites confidently list schools.
But those details are usually repeated without documentation.
Her professional credits show that she successfully entered Hollywood wardrobe work.
Whether she learned through formal fashion education, on-the-job experience or both is not reliably public.
Why Kacy Byxbee Keeps Her Life Private
Kacy’s privacy is one of the most consistent things about her story.
Consider the circumstances.
Her partner starred in one of CBS’s biggest police dramas.
His father starred in The Godfather.
Kacy herself worked inside television.
Their daughter is part of a famous acting family.
Yet Kacy rarely gives interviews.
There is no major reality show.
No constant social-media coverage.
No public discussion of arguments, parenting or finances.
That level of privacy over more than a decade looks deliberate.
Is Kacy Byxbee on Instagram?
Some websites associate a private social account with Kacy.
However, there is no major verified public Instagram account that functions like a celebrity profile.
That means readers should be careful about assuming every “Kacy Byxbee” social account is authentic.
It also means much of her family life cannot be responsibly reconstructed through social media.
Kacy has apparently chosen not to make her personal life a public content business.
Is Kacy Byxbee Still With Scott Caan in 2026?
There is no credible public report reviewed here announcing a breakup.
Recent profiles continue referring to Kacy as Scott’s longtime partner.
At the same time, they do not constantly make public appearances together.
That should not automatically be interpreted as relationship trouble.
Kacy and Scott have always been private.
The safest current answer is:
Publicly available information continues to identify Kacy Byxbee as Scott Caan’s longtime partner, with no reliably reported separation.
What Is Kacy Byxbee’s Net Worth?
Kacy’s net worth has never been independently verified.
Internet articles provide numbers ranging from several hundred thousand dollars to millions.
Those estimates usually have no financial documents behind them.
To calculate a real net worth, we would need information about:
salary,
property,
investments,
business ownership,
savings,
and liabilities.
Those details are private.
Her years working in television certainly mean she earned her own income.
But that does not allow us to produce a precise fortune.
Scott Caan’s wealth should also not simply be copied and labeled as Kacy’s.
Kacy’s Life Is Different From Scott’s
Scott has spent decades in front of cameras.
Kacy spent much of her entertainment career behind them.
That difference is interesting.
Scott’s job required:
interviews,
premieres,
publicity,
photographs,
and being recognized by strangers.
Kacy’s job involved making sure actors were ready to appear on camera while she herself remained outside the frame.
Even after their relationship became public, that pattern largely continued.
Scott remained visible.
Kacy remained quieter.
What We Actually Know About Kacy Byxbee
Once weak claims are removed, her story becomes quite clear.
Kacy worked in the costume department on Sofia Coppola’s Somewhere.
She later became a regular wardrobe professional on Hawaii Five-0, receiving credits for 69 episodes from 2011 through 2014.
She met actor Scott Caan through that production, according to entertainment reporting.
They were publicly together by 2013.
In June 2014, Scott’s representative confirmed Kacy was expecting their first child.
Their daughter Josie James Caan was born on July 9, 2014.
Kacy later received another wardrobe credit on All at Once.
She has occasionally attended premieres with Scott.
They have remained very private.
What we do not reliably know includes:
her exact birth year,
exact age,
detailed education,
parents’ identities,
current occupation,
personal finances,
and any confirmed wedding date.
Those details should not be invented simply to make a biography look complete.
Final Thoughts
Kacy Byxbee’s biography is interesting because she is connected with Hollywood from two different directions.
She actually worked in the industry herself.
And she built a life with a famous actor.
Her career began behind the scenes.
She worked on Somewhere and then became part of the wardrobe department on Hawaii Five-0.
That television job changed more than her résumé.
It also introduced her to Scott Caan.
Scott was already well known from the Ocean’s movies and was becoming one of CBS’s most recognizable television actors through his role as Danny Williams.
Their relationship developed quietly.
By 2013, Scott was publicly talking about his girlfriend.
The next year they welcomed their daughter, Josie James Caan.
Josie’s middle name created another connection with the famous Caan family by honoring Scott’s father, James.
But Kacy never seems to have wanted that connection to become her entire identity.
She continued working behind the camera.
She attended some premieres.
Then she returned to private family life.
That is why so many questions about her still have uncertain answers.
People want to know her age.
They want to know whether she and Scott secretly married.
They want to know her net worth.
They want to know what she does every day.
Kacy simply has not made those things public.
For readers searching for Kacy Byxbee, the clearest answer is this: she is a genuine television and film wardrobe professional, Scott Caan’s longtime partner and the mother of their daughter Josie James Caan. Her strongest career credit is her multi-season work on Hawaii Five-0, and despite years of proximity to Hollywood fame, she has successfully kept most of her own life private.
