Julia Stiles is married to Preston J. Cook, a camera professional she met while working on the 2014 thriller Blackway. The couple married in September 2017 and have now reached nine years of marriage. Their relationship remains largely private, but Stiles has recently offered a few personal glimpses into their life together as she takes on a new chapter with Dancing With the Stars.
Stiles and Cook have built a family of five while maintaining a relatively low public profile. They have three children, and Stiles has deliberately kept some details about her youngest child away from the spotlight.
The actress recently marked her ninth wedding anniversary with Cook on social media. Her message highlighted his support while she balances family responsibilities with the demanding schedule of her current television appearance.
The anniversary update also gave fans a timely look at a relationship that began on a movie set more than a decade ago.
Julia Stiles’ Husband Is Preston J. Cook
Preston J. Cook is a camera assistant who has worked extensively behind the scenes on film and television productions.
Unlike his wife, Cook does not have a major on-screen presence. His career has focused on camera work, placing him behind the camera on several well-known Hollywood productions.
His credits include projects such as The Revenant, Deadpool, Jason Bourne, War for the Planet of the Apes, Overboard and Skyscraper. He has also worked on television productions, including the series Riviera.
Cook’s professional background is particularly relevant to his relationship with Stiles because the pair first met through their shared work in the entertainment industry.
Their relationship began away from the traditional Hollywood spotlight. Both were working on a film, and their professional connection eventually became a personal one.
That beginning has remained an important part of their story.
How Julia Stiles Met Preston J. Cook
Stiles and Cook first met in 2014 while working on Blackway.
Stiles starred in the thriller, while Cook worked in the camera department. Their first meeting came during production, giving them an opportunity to spend considerable time together while filming.
The relationship developed after they met on the set.
The two continued to work in the same industry, and their professional lives crossed again on later projects. Cook worked on Jason Bourne, where Stiles reprised her role as Nicky Parsons.
Their careers also brought them together on the television series Riviera. Stiles starred in the series, while Cook worked in the camera department.
Working on the same productions gave the couple a unique opportunity to understand the demands of each other’s careers.
Stiles previously discussed the experience of working with Cook on Riviera. The production involved filming in Europe, and having Cook working on the same project meant they did not have to spend months apart.
That shared professional experience became an important part of their relationship.
When Did Julia Stiles and Preston J. Cook Get Engaged?
Cook proposed to Stiles in December 2015 during a trip to Colombia.
The engagement happened roughly a year after the couple met.
Stiles later discussed the proposal during television interviews. She explained that Cook’s proposal came as a surprise, even though there had been small clues that he was thinking about jewelry.
She shared news of the engagement publicly around Christmas 2015.
At the time, Stiles expressed her happiness about the relationship and described Cook warmly.
The engagement period lasted into 2017. Stiles and Cook did not rush into a large wedding, and she previously acknowledged that wedding planning was moving slowly.
Their eventual ceremony reflected the couple’s preference for privacy.
Julia Stiles and Preston J. Cook’s Wedding
Stiles and Cook married in September 2017.
The ceremony took place during Labor Day weekend on a beach in Seattle, Washington. It was an intimate event attended by only a small group of people.
The couple later confirmed their marriage publicly.
Stiles shared a photograph showing the couple’s hands and their wedding rings. At the time, she was pregnant with their first child.
Her humorous caption referred to the event as a “shotgun wedding,” but the ceremony itself was deliberately small and private.
The wedding took place only weeks before the birth of their first child.
Rather than organizing a large Hollywood celebration, Stiles and Cook chose a much quieter ceremony with close friends.
That decision fits the way they have handled their relationship ever since. While Stiles has remained a recognizable actress, she has generally avoided making her marriage a constant subject of public attention.
How Long Have Julia Stiles and Preston J. Cook Been Married?
Stiles and Cook have been married since September 2017.
In September 2026, Stiles celebrated their ninth wedding anniversary.
She marked the occasion with a social media post featuring a throwback photograph from their wedding. Her message described Cook affectionately and thanked him for supporting her during her current professional commitments.
The timing of the anniversary was significant.
Stiles was preparing for her Dancing With the Stars appearance, which required an intense rehearsal schedule. Her husband was helping manage responsibilities at home while she concentrated on learning ballroom routines.
Stiles’ anniversary message gave fans one of the clearest recent glimpses into the couple’s relationship.
Although she does not frequently post about Cook, the anniversary tribute showed that he continues to play an important role in her personal life.
Julia Stiles and Preston J. Cook Have Three Children
The couple are parents to three children.
Their first child, Strummer Newcomb Cook, was born on October 20, 2017. His arrival came only weeks after his parents married.
Stiles announced his birth with a photograph of her newborn son’s hand holding Cook’s thumb.
The couple later welcomed their second child, Arlo, in January 2022.
Stiles announced Arlo’s arrival with a photograph showing the baby’s feet. The actress described the new addition as another source of love for the family.
Their third child was born in 2023.
Stiles kept the third pregnancy private and did not publicly announce it before the birth. She revealed that she had welcomed another baby during an interview in 2024.
The actress has remained selective about information concerning her youngest child.
Recent coverage continues to identify the couple as parents of three children. Stiles has discussed motherhood publicly at times, but she has not turned her children’s private lives into regular social media content.
Who Are Julia Stiles and Preston Cook’s Children?
The couple’s oldest child is Strummer Newcomb Cook.
Strummer was born in October 2017, shortly after Stiles and Cook’s wedding. He was their first child.
Their second child is Arlo, who was born in January 2022.
The couple’s youngest child was born in 2023. Stiles initially kept the pregnancy private and later confirmed the birth.
There has been limited public information about the youngest child compared with the older children.
Stiles’ approach has been consistent with her broader effort to protect her family’s privacy. She occasionally discusses motherhood but generally avoids providing extensive personal details about her children.
In 2026, Stiles has spoken about her children in connection with her participation in Dancing With the Stars.
She has explained that her children see her practicing dance at home. Her family has therefore become part of the routine surrounding her latest professional challenge, even though they remain mostly outside the public spotlight.
Preston Cook’s Career Behind the Camera
Cook’s career has developed on the technical side of the entertainment industry.
His work as a camera assistant has taken him onto major film sets and television productions.
Some of the projects associated with his career include The Revenant, Deadpool, Jason Bourne and War for the Planet of the Apes.
He has also worked on Overboard and Skyscraper.
His work on Jason Bourne was particularly notable because Stiles appeared in the film as Nicky Parsons. The production marked another professional connection between the couple after their initial meeting on Blackway.
Cook also worked on Riviera, the television drama starring Stiles.
Their shared experience in the entertainment industry has given them a common understanding of production schedules, travel and the pressures associated with working on film and television projects.
Unlike Stiles, however, Cook has largely remained outside the celebrity spotlight.
A Marriage That Has Stayed Out of the Spotlight
Stiles has maintained a different approach to celebrity relationships than many public figures.
She has never made her marriage a central part of her public identity. Instead, occasional photographs and anniversary messages provide most of the glimpses fans receive.
Cook also maintains a low public profile.
That combination has allowed the couple to build a family without constant media attention.
They have appeared together publicly at selected events, including premieres and industry gatherings. However, joint appearances have never become a regular feature of their public lives.
The couple’s privacy became especially apparent with the birth of their third child.
Stiles did not announce the pregnancy publicly. Instead, she revealed that the family had welcomed another baby when discussing her professional work in 2024.
The decision allowed her to experience another major family milestone away from the intense attention that often surrounds celebrity pregnancies.
Preston Cook’s Role in Julia Stiles’ Current Career
Cook’s support has become especially visible as Stiles takes on a new challenge in 2026.
Stiles joined the cast of Season 35 of Dancing With the Stars, returning to the dance world more than two decades after Save the Last Dance became one of her best-known films.
Her participation requires regular rehearsals and a demanding schedule.
Stiles has discussed how her family has responded to her dancing at home. Her children have watched her practice, while Cook has also been part of the household routine surrounding her preparation.
During her anniversary message in September 2026, Stiles specifically thanked Cook for helping manage things at home while she pursued her dance opportunity.
That public acknowledgment offered a glimpse into the partnership behind her current professional commitment.
Julia Stiles’ Family Life During Dancing With the Stars
Stiles’ current television appearance has brought renewed public interest in her personal life.
Her husband and children remain an important part of the story because the actress is balancing rehearsals with life as a mother of three.
She has described her children as familiar with her dancing because she practices at home.
The children have even become informal participants in her rehearsals. Stiles has said that she sometimes practices while holding them.
Cook has also been present during these moments at home.
That family involvement gives her current dance journey a more personal dimension. Her latest professional challenge is not taking place separately from her family responsibilities.
Instead, Stiles has incorporated the experience into her everyday life.
