Robert Pattinson may have set tween hearts aflutter in the Twilight series, but the actor revealed he's really method at heart: In an interview with the German magazine Interview, he claims he couldn't simulate masturbating in a scene from 2008's Little Ashes, so he just did it for real: "[Faking it] just doesn't work. So I pleasured myself in front of the camera. My orgasm is recorded for eternity."

Something tells us he wasn't thinking of Kristen Stewart.

In the movie, Patinson plays surrealist painter Salvador Dali, and has an ill-fated liaison with gay writer Federico García Lorca (Javier Beltran).

"We were all hanging out by the pool, trying to loosen up. I was nervously clinging to the edge -- and before I could turn around, the Spaniard was already naked," he says of another scene, when he and Beltran have sex."He happily swam towards me... And I didn't have a clue how to react."

Maybe it's for the best, then, that R-Pats didn't get picked as Christian Grey in the 50 Shades of Grey movie. Below, Javier Beltran and Robert Pattinson get intimate in Little Ashes.
