Pattinson is a manic depressive

Robert Pattinson has admitted he suffers from manic depression.

The Twilight hunk's shock admission is sure to stun his legion of female fans, but he has revealed he suffers from the condition whenever he is in a relationship.

He told New magazine, "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," he added.
