Actress Rachel McAdams has reportedly ended her relationship with Michael Sheen, according to US Weekly.

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.

McAdams, who resides in Toronto when she's not off filming movies around the world, had floor seats for Monday night's NBA game between the Washington Wizards and Toronto Raptors at the Air Canada Centre.

While there, the actress debuted her bright new red hair, she was serenaded by "The Raptor," the Raptors' mascot.

McAdams will next appear in Terrence Malick's drama "To the Wonder," in theaters April 12. She was on hand at the premiere of "The Twilight Saga: Breaking Dawn - Part 2" last November, in which Sheen plays the Volturi vampire Aro. He'll next appear in Tina Fey and Paul Rudd's comedy "Admission," in theaters March 22.
