We've all heard the adage, "Once a cheater, always a cheater," so if we were Robert Pattinson, we'd be worried. Off-and-on love Kristen Stewart cheated on ex-beau Michael Angarano with Rob, and then she cheated on Rob with her "Snow White and the Huntsman" director, Rupert Sanders. Sounds like K.Stew has a thing for her colleagues! The actress is set to shoot rom-com "Focus" in April, and fortunately for Rob, Ben Affleck just dropped out of playing her on-screen love. So maybe Rob's Christmas miracle came early!
