Our favorite couples keep breaking up!

It was Michelle Williams and Jason Segel yesterday, and now Us Weekly says Rachel McAdams and Michael Sheen have ended their relationship.

Rachel, 34, and Michael, 44, met on the set of Midnight in Paris and started dating afterward, first showing their love in public in October 2010. She previously dated Ryan Gosling (who is now with Eva Mendes or we'd push for a Notebook reunion) and Michael has a daughter with Kate Beckinsale.

It does seem like right around Valentine's Day, and the end of awards season, a lot of couples just call it quits. We're scared to hear who is next!
