So what if it's only the first week of February. That's not gonna stop us from nominating Rachel McAdams and Michael Sheen as cutest couple of the year.

The PDA-disposed duo was also spotted grabbing lunch and stopping by a comic book store on Sunday, which also happened to be Sheen's birthday. "Michael and I never spend more than three weeks apart," Rachel recently told the Sunday Telegraph of her British beau of more than a year. "We rack up a lot of air miles."
