Robert Pattinson shocked at male nudity

Robert Pattinson is bemused by the growing number of male actors who are willing to strip off on screen, branding it "crazy".

The Twilight hunk has blamed the increase on his vampire series co-star Taylor Lautner, who wowed cinemagoers with his impressive physique.

Pattinson says, "It seems like every single actor in the world is doing a Taylor Lautner scene. It's crazy. They have a scene where they walk out with a 12-pack. It's like, 'Really? You're playing a normal guy. That doesn't make any sense."

And despite going topless himself in the Twilight movies, Pattinson has vowed to keep his clothes on in future - unless he hits the gym to get in shape.

He adds, "I'd have to make a lifestyle change if I wanted to do shirtless acting."
