Katherine and RumerI mean Rumer Willis and Katherine McPhee? Quite a cast. The film is called House Bunny and stars Anna Faris who is actually a good actress. The film is about a fired Playboy funny who takes refuge in a sorority house. A sorority house where Rumer Willis (who is literally friends with every young female celebrity) and Katherine McPhee belong. And now Katherine McPhee (who I guess is knocked-up in the film) and Rumer are of course the best of friends. I hope Anna can save this film because I doubt these two can.
