Naomi Watts, Liev Schreiber reunite to celebrate with son Sasha

The actor and her ex reunited temporarily over the weekend for a celebration with Sasha. Although she didn't specify exactly what the occasion was, she shared a sweet selfie of the trio on her Instagram Stories. The amicable exes posed for a snap outside a restaurant, which Watts captioned, "So proud of you @sashapeteschreiber," with three red heart emojis. The British-born Australian actor tagged her ex and son in a second post from inside the eaterie. Watts and Schreiber first started dating in 2005. They welcomed Sasha back in 2007, and his brother Kai, now 15, in 2008.
