Robert Pattinson
Twilight fans may be disappointed to hear that their leading man is sick of his nick name.

On the media circuit promoting "Bel Ami" and his upcoming "Cosmopolis", 26-year-old Pattinson admitted that he really dislikes his nickname “RPattz”.

The London born actor told The Guardian he wants to strangle the person who came up with the term!

"When I got this part [Cosmopolis] , every single article that came out was 'RPattz's struggle for credibility!'; I don't understand who invented that thing, 'RPattz,' I want to strangle them," he told the paper.

"But once you've made that step, everything afterwards is not like, 'RPattz's continuing struggle for credibility!' You've got to come up with something else, so it gets a little bit easier."

Pattinson admitted a lot of people expect him not to be the brightest penny.

"It is surprising the amount of people who think I'm going to be really dumb," he says. "I think they think anyone who has done teen movies is just an idiot. I don't know, maybe I am. Some of the best actors, if you talk to them, they're not the smartest people in the world."
