Well we never saw this one coming.  Kristin Stewart and Robert Pattinson have started dating, friends have told the New York Daily News. Stewart has been dating actor Michael Angarano but now sources say she’s switched her attention to her on-screen lover. “Robert and Kristen spent a lot of time alone together when they filmed the first Twilight movie. They’d stay up most of the night talking, laughing and playing music,” an insider claims. “Although [Robert] knew Kristen had a boyfriend, he made no secret of the fact that he was crazy about her.” Cute! Although we’re sure there will be a lot of Pattinson fans out there upset to hear the news.
