Rachel McAdams headed out last night to see the musical Avenue Q in LA. The actress is back in California after a recent getaway with her boyfriend Michael Sheen to Ireland, where they reportedly met up with some of his extended family. The Sheen meet-and-greet may have been a big step for the couple, who have been dating for less than a year after meeting last Summer on the French set of Woody Allen's Midnight in Paris. They went public with their love a few months later with a PDA-filled walk through Toronto, but really upped the hotness factor with an airport make-out in December. Michael is clearly Rachel's real-life leading man, but she looks mighty cozy with the hot Ben Affleck in a new promo picture from their still untitled Terrence Malick film.
