Rachel McAdams is reportedly single again after splitting from her beau of two years, actor Michael Sheen.

The couple met while filming the Woody Allen movie “Midnight In Paris” and eventually became close, though McAdams has said that she’s wary of starting a relationship while on-set.

“Michael and I didn’t get together while we were filming Midnight in Paris, which I feel strongly about not doing when I’m working. We became quite good friends, which I think is a great way to start,” McAdams says. “I felt very blessed to have made a Woody Allen film in Paris together.”

McAdams has dated her co-stars previously, including Ryan Gosling, whom she was engaged to after they filmed “The Notebook” together. And while no reason has been offered for the breakup, McAdams has said in the past that it is notoriously difficult for celebrities to maintain relationships when they are often called upon to travel for work.

“Michael and I never spend more than three weeks apart — we rack up a lot of air miles — but you have to be quite adaptable in this business whether you are in a relationship or not. Trying to establish roots somewhere is a bit of a joke,” she said.
