Although she hasn’t yet turned 18, Naomi Watts’ daughter, Kai Schreiber, is already making waves in the modeling industry. Her runway debut left many netizens impressed.

On March 9, 2025, both IMG Models Worldwide and Kai Schreiber took to Instagram to share photos and video footage of the young model on the catwalk. At the time, the 16-year-old who uses the “her” pronoun on Instagram, was making her runway debut for Valentino at Paris Fashion Week.

Some images captured Naomi Watts and Liev Schreiber’s daughter sitting in a chair with bleached eyebrows as she prepared for the show. A headshot of Kai dressed in her Valentino outfit was also included in the carousel alongside other models.

Footage gave fans a glimpse of the teenager walking out of a red public toilet setup. A close-up image of her face was also featured in the post. On her own Instagram post, Kai shared a photo explaining her look.

The image revealed that she wore a python knit short dress paired with a brown and purple feather collar. Her ensemble also included a beige and pink headband, dark Havana acetate sunglasses with blue lenses, and white sandals with a rose strap.

Kai captioned her post, “omggg my heart is so full 💗 ilysm (I love you so much). [sic]” Her father proudly uploaded a picture of his daughter on the runway and wrote, “Ladies and gentlemen the one, the only, the indomitable @kaischreiberr!”

Seeing Liev’s daughter on the runway, one person called her “Stunning” and added, “She looks so like her mom.” Someone else described Kai as “Stunning and elegant.”

Celebrating with Liev, a netizen wrote, “Wow!! Proud Daddy!! She’s stunning… she’s made for this!!! Congratulations 💕💕💕.” Naomi also shared images and clips of her daughter’s runway debut and captioned the post, “That’s my @maisonvalentino baby! I’m squealing with pride. Ilysm @kaischreiberrr ❤️”

The Instagram post included a looped clip of Kai dressed in her Valentino outfit, playfully shaking her body while someone recorded her.

Reacting to the post, a fan exclaimed, “Wow! So exciting. Kai was born to catwalk 😻❤️😻.”

Speaking directly to the actress, one netizen commented, “I can see your face in hers.” Impressed by the teenager’s confidence on the runway, another person remarked, “You are clearly a natural, well done 🤩.”

Someone else simply wrote, “Kai ❤️ goddess,” on the model’s page. The praise continued with a fan stating, “I see the next Kate Moss in you! 🙌🔥,” while another added, “What an incredible moment for you, Kai!!! Cheering you on from the sidelines 🙌🙌🙌 GORGEOUS ❤️❤️.”

Kai’s father also left her a supportive comment, writing, “Beyond beyond Kai,” while her mother wrote, “Be still my beating heart!! 🙌♥️🙌 bravo darling ILSM and what a show!! @maisonvalentino 💥💪.” The teenager later shared stills from the fashion show on her Instagram Story.

In a 2019 interview, Naomi opened up about her children, her sons, Sasha and Samuel Kai, whom she shares with her ex-husband. The actress revealed that the preteen siblings had begun showing an interest in drama.

Their passion was so strong that they spent part of that summer at a camp specializing in performing arts. Explaining the situation, the star said, “It seems they’ve got the bug.”

Naomi admitted that her feelings about their interest were “definitely mixed,” but she and Liev have always aimed to provide their sons with a more stable and structured upbringing than they had. She noted, “We’re doing things very differently.”

When asked whether providing stability and structure had become more challenging since she and Liev divorced in 2016 after 11 years together, Naomi responded, “I’m pretty proud of us, corny as that may sound. We’ve made it our absolute priority to be good and kind to each other, and we’re absolutely committed to that.”

Speaking about her children, Kai is not the only one who has received attention from their parents over the years. For instance, in July 2023, Sasha was the focus of a heartfelt sweet sixteen tribute from his mother.

Naomi wrote, “Happy 16th to my darling boy. I cannot believe how fast this happened?!” Her post featured a carousel that began with a photo of her laughing while holding the birthday boy around the waist.

She continued, “Thank you for still letting me hold your hand sometimes. Even though I know you probably just forget to pull it away. Happy birthday! What a beautiful young man.” Several celebrities joined in the celebration, including Molly Ringwald who commented, “Happy birthday! What a beautiful young man.”

Julianna Margulies, noticing the resemblance between Naomi and her son, said, “Omg! He’s you! He’s totally you! So gorgeous!” Meanwhile, Gina Gershon enthusiastically added, “Happy Birthday Sasha!!!!” and Paulina Porizkov wrote, “What a lovely photo of you two.”

Sasha’s father also marked the occasion with a social media tribute. “Happy Birthday, Handsome!” Liev captioned a close-up photo with his son. The “Ray Donovan” actor and Naomi have been successfully co-parenting their children since their breakup.

In June 2022, Naomi posted a group selfie featuring her children, her then-boyfriend-turned-husband Billy Crudup, and Liev and his then-girlfriend and now-wife, Taylor Neisen, at Kai’s graduation. She captioned the post with the hashtag “modern family.”

On the same day, Liev congratulated Kai by uploading a photo of her with his ex.

Naomi sparked marriage rumors when she was spotted on June 9, 2023, wearing a white lace Oscar de la Renta dress. A series of paparazzi shots captured the actress holding a bouquet of white flowers while standing beside her current husband.

Billy appeared in a navy suit while they were near their New York City apartment. The Australian actress confirmed their nuptials the next day on social media by sharing a photo of them standing on the steps of what appeared to be a courthouse, captioned, “Hitched.”
