Rachel McAdams and Michael Sheen have split.
The couple ended their relationship, according to Us Weekly, which reports that "The Vow" actress is back on the market.
McAdams, 34, and Sheen, 44, met on the set of Woody Allen's 2010 film "Midnight in Paris" — their characters were romantically entangled when Sheen played Owen Wilson's rival in the film. However, McAdams has said that Sheen and she did not hook up while filming.
"I feel strongly about not doing [that] when I'm working," she said in a January 2012 interview with the Sunday Telegraph's Stella magazine. "We became quite good friends, which I think is a great way to start. I felt very blessed to have made a Woody Allen film in Paris together."
The pair took their relationship public in October 2010.
The "Mean Girls" actress was previously attached to her "The Notebook" costar Ryan Gosling, whom she began dating in 2005 and was briefly engaged to. But the couple called it quits in 2007. British actor Sheen dated actress Kate Beckinsale from 1995 until 2003; they have a 14-year-old daughter, Lily.
