In an interview with New magazine, the Twilight actor described himself as manic-depressive – also known as bipolar disorder.

Rob, 24, explained: “You over-analyse everything – you analyse how if you say one thing, someone likes you, and if you say another, they don’t. You begin to experiment on people, which isn’t good for real life. I don’t think I’m very romantic any more – just manic depressive.”
