mcadams-sheen-split.jpgMichelle Williams and Jason Segel weren't the only ones announcing a split this week -- turns out Rachel McAdams and Michael Sheen have ended their relationship as well!

The couple dated for nearly two and a half years, and though they have yet to issue a comment on the matter, a source confirms to Us Weekly that they have parted ways.

McAdams, 34, and Sheen, 44, met on the set of Midnight in Paris in 2010, but McAdams insists that the two didn't hook up while filming. "I feel strongly about not doing [that] when I'm working," she told 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."

McAdams was previously linked to Ryan Gosling (the two started dating in 2005, got engaged and ended things in 2007), and Sheen was with actress Kate Beckinsale from 1995 until 2003.
