Jamie Campbell Bower Reveals 'New Moon' Nude Scene

'We just all sit there, completely naked, for one scene,' the actor says of him and two other Volturi vampires.

SAN DIEGO — Lucky Twilighters who made the trek to Comic-Con last week were able to hoot and holler as two never-before-seen clips were unveiled — one featuring [movieperson id="373803"]Taylor Lautner[/movieperson] taking off his shirt, and another featuring [movieperson id="365131"]Robert Pattinson's[/movieperson] porcelain-white six-pack. One might think that all this "New Moon" flesh is what gave the film its PG-13 rating.

But according to the newest "Twilight" hunk, there's one more top-secret scene sure to raise some eyebrows.

"We just all sit there, completely naked, for one scene," revealed [movie id="414921"]"New Moon"[/movie] actor Jamie Campbell Bower, talking about a racy moment that was added into the upcoming film. "Yeah, it's me, Michael Sheen and Christopher [Heyerdahl]; we just sit there, naked."

In the November 20 film, Bower plays Caius — an evil member of the Volturi vampire clan. Sheen plays their leader Aro, and Heyerdahl has been cast as Marcus. As any good Twilighter knows, the leader of the Cullen clan has a history with the centuries-old bloodsuckers, and when it came time to shoot "New Moon," director Chris Weitz wanted to depict that backstory.

"We try and kill Bella, try and convince Edward to come and stay with us and live with us, because Peter [Facinelli]'s character had come and lived with us before," Bower explained. "There's a scene with the [Carlisle meeting] background to it, and it's good fun.

"We're just chilling out, just watching the game and having a Bud," Bower laughed of the scene, which depicts Carlisle hanging with the Volturi back in the day. "No, that doesn't sound right. I'm so British. I can't say that stuff."

In actuality, the scene has a fully clothed Carlisle visiting the Volturi in Italy, only to locate Aro, Caius and Marcus in a bathhouse. "It's a full-body shot, and then Peter comes in, and it all gets a bit awkward," Bower said. "[Carlisle] is clothed completely. They're bathing in sort of a Roman bath kind of thing."

MTV News was on the scene at the 2009 San Diego Comic-Con. Visit MTVNews.com, Splash Page, the MTV Movies Blog and Hollywood Crush for videos, interviews and the latest news on "New Moon," "Iron Man 2" and everything in between.
