Kristen Stewart Is Afraid That Robert Will Hook Up

The newest rumors about Kristen Stewart and Robert Pattinson are as intriguing as they are believable: Kristen is supposedly getting nervous that Pattinson will hook up with his co-star Emilie de Ravin of Lost (aka Claire). What's a Twilight star to do, especially when she's got a mullet and is all the way across the country filming?

A source admitted to Star magazine that "Kristen’s been calling him nonstop since he’s been in New York and gets uneasy when he doesn’t answer. She’s nervous he’ll fall for Emilie." According to the source, Kristen Stewart thinks that it's just a matter of time before now-single Emilie and frustrated-in-love Robert Pattinson get busy.
