Actors Liev Schreiber and Naomi Watts have ended their relationship after 11 years of being together.

“Over the past few months we’ve come to the conclusion that the best way forward for us as a family is to separate as a couple. It is with great love, respect, and friendship in our hearts that we look forward to raising our children together and exploring this new phase of our relationship," the couple told Entertainment Tonight in a joint statement. “While we appreciate your curiosity and support, we ask the press to be mindful of our children and respect their right to privacy.”

The couple had been together since 2005, but never got married. They have two children together — Alexander “Sasha” Pete, 9, and Samuel “Sammy” Kai, 7.

They’ve regularly made public appearances, the latest being the Venice Film Festival and Toronto International Film Festival at the beginning of the month, where they were promoting their latest film — “The Bleeder.” In the movie, Schreiber plays boxer Chuck Wepner, while Watts is portraying the role of Linda Wepner, his second and current wife.

While Watts, 47, was missing beside Schreiber, 48, at the Emmy Award this year, her place was taken by Sasha, who walked beside his dad dressed up in a suit and bow-tie. Watts took to social media to share a picture of the father-son duo.

 “There are days where you feel like you're supermom and doing really well and got it handled, and then there are days where you're like, ‘Ah! I can't do this!’” Watts told ET earlier this year. “It's like any working mom, I think. It's a balance.”

The power couple’s separation comes soon after Angelina Jolie and Brad Pitt announced their split last Tuesday.
