Naomi Watts Shares Rare Photos of Son Sasha for His 18th Birthday — and Fans Say He Looks Like a Young Brad Pitt

As Naomi Watts marked a major family milestone this week, fans were treated to a rare look at her son Sasha. Many couldn't help but notice his striking resemblance to a younger version of a Hollywood heartthrob.

Naomi Watts shared rare photos of her son Sasha Schreiber, whom she shares with ex-partner Liev Schreiber, in a touching Instagram post honoring his 18th birthday.

"Happy birthday sweet, darling @sashapeteschreiber," Naomi wrote in the caption of her July 25 carousel. "18 today — and ready for the world! Cannot believe it. [sic]"

"Have so loved watching you grow into the kindest, most wonderful young man, [sic]" she continued. "Thank you for making me a first time mum."

The 56-year-old actress, who also shares 16-year-old daughter Kai with Liev, included several personal snapshots in the post. Among them was a solo image of Sasha looking grown up, along with three other photos showing their bond over the years — including a baby picture and two more recent shots of mother and son smiling together.

Fans couldn't help but notice Sasha's striking resemblance to Brad Pitt, particularly when the Hollywood star was still young. "He looks like a very young Brad Pitt. Happy Birthday young man. All the best, [sic]" one fan wrote. "He looked like young Brad Pitt 😅, [sic]" another echoed. "First picture, i thought its young Brad pitt, [sic]" a third person said.

Sasha's birthday comes shortly after a family milestone: his high school graduation. Naomi and Liev, who ended their relationship in 2016 after 11 years, reunited last month to celebrate the occasion alongside their current spouses, Taylor Neisen and Billy Crudup, respectively.
