After nine years together, director Darren Aronofsky and actress Rachel Weisz have split.
"Rachel Weisz and Darren Aronofsky have been separated for some months," their rep tells TMZ. "They remain close friends and are committed to raising their son together in NYC."
Both are seeking joint custody of their son Henry, 4.
The news comes as Aronofsky is set to release Black Swan, the Natalie Portman ballet drama that is already generating Oscar buzz.
Weisz, 40, and Aronofsky, 41, began dating when he directed her in the sci-fi love story The Fountain.
They announced their engagement in 2005 but never wed.
"I found myself a sophisticated, educated American," she told Jay Leno in 2006. "He's not an actor. He's traveled the world. He knows where Europe is, unlike a lot of Americans. He's very cultured, but he's all man."
