No word on what could have caused this alleged breakup but the couple does have a long-distance relationship. McAdams resides in Toronto, Canada, while Sheen bounces between Wales and Los Angeles.

This wouldn't be the first high-profile breakup for the stars. The actress broke off her engagement to her Notebook co-star Ryan Gosling in 2007, while Sheen called it quits with the mother of his child, actress Kate Beckinsale, after an eight-year relationship.
