Naomi Watts Shares Birthday Photos of Son, Sasha, 18, Sparking Online Buzz

The British actress and her ex-boyfriend Liev Schreiber share two children, Sasha and Kai, who occasionally make headlines thanks to their high-profile parents.

Naomi Watts recently shared photos of her son, Sasha, in celebration of his 18th birthday, prompting fans to flood the comments with admiration and surprise. Many couldn’t get over how much he resembles his famous mom, while others drew comparisons to a current Hollywood star in his younger years.

Naomi marked the major milestone with a heartfelt tribute on Instagram, writing, "Happy birthday sweet, darling @sashapeteschreiber 18 today—and ready for the world! Cannot believe it.😊😭 Have so loved watching you grow into the kindest, most wonderful young man. Thank you for making me a first time mum ♥️."

Her post featured a carousel of photos capturing moments from Sasha's childhood to his teenage years. One photo showed baby Sasha perched on Naomi's waist, looking absolutely adorable.

Another picture of the two shows them posing for a joyful selfie in sunglasses and a third showing her fixing a flower lapel on his sharp black suit.

The cover photo, a solo shot of Sasha looking straight into the camera, had fans doing double takes. In the comments, admirers were quick to point out his striking resemblance to both his mother and another familiar face — Brad Pitt.

One fan kept it simple and sweet, saying, "You're almost identical! Happy Birthday ❤️." Another person gushed over the resemblance, "He is your twin happy birthday, such a handsome boy." A surprised follower wrote, "Omg i thought this is you with short hair [sic]."

Someone else echoed the sentiment, "What a beautiful young man- your double!" Other people focused on Brad with one user saying, "He looks like a very young Brad Pitt. Happy Birthday young man. All the best."

That observation was shared by others, including someone who commented, "First picture, i thought its young Brad pitt [sic]." Another person simply said, "Thought that was bradd [sic]." And one fan concurred, "He looked like young Brad Pitt 😅."

In March, it was Sasha's younger sister, Kai, who had fans talking when she joined Naomi Watts for a striking appearance at the New York premiere of "The Friend." Held at the iPic Theater, the event saw the mother-daughter duo turn heads on the red carpet with their eye-catching ensembles, quickly drawing public attention.

Naomi, 56, arrived in a sophisticated white sleeveless gown featuring draped fabric and black fur-like accents. The dress had a high neckline and an elegant asymmetrical design. She paired the look with a sleek blonde bob, natural makeup, and a radiant smile.

Beside her, Kai made a bold fashion statement. She wore a strapless pink ruched top with a sweetheart neckline, layered under a cropped navy blazer adorned with red polka dots.

A black bow accent on the jacket added a chic touch. Her skirt was black, tiered, and ruffled, completing the avant-garde ensemble. Kai's straight blonde hair, bleached eyebrows, and minimal jewelry complemented the edgy aesthetic.

Following the premiere, People magazine shared a post on Instagram featuring the duo, captioned, "Double the glam! #NaomiWatts hit 'The Friend' premiere with her daughter, #KaiSchreiber, for a stunning mother-daughter red carpet moment."

The post quickly attracted reactions from social media followers. Some admired their looks, while others commented on Kai's expression and style choices.

One person wrote, "This kid nowadyas with their style and attitude [sic]." A different commenter questioned, "Would it hurt to not look tormented [?]"

The conversation continued on Facebook, where many noted Kai's resemblance to her father, actor Liev Schreiber. One comment read, "She's a look alike [sic] for her dad," while another insisted, "Please! The girl looks like her father!"

Some netizens focused on her expression, with one stating, "She looks bored…or was made to go with mom..lol."

Others commented on her appearance, saying, "Cause she lost her eyebrows [sic]!" and another one declared, "Look like a doll [sic]." Yet another commenter divulged, "Another one with no eyebrows [sic]."

While Naomi has long been a staple on the red carpet, Kai has been stepping into the spotlight more frequently in recent years. As the daughter of two Hollywood stars, she continues to attract attention for her evolving fashion choices and public appearances.

Her growing presence in the public eye isn't limited to red carpet events. Although she hasn't yet turned 18, Kai is already making waves in the modeling industry. Her recent runway debut left many netizens impressed.

On March 9, 2025, IMG Models Worldwide and Kai 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 and Liev'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. Kai also shared a photo on Instagram explaining her look.

The image revealed that she wore a python knit short dress 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."
