Robert Pattinson is known for his passionate lovemaking scenes in the Twilight films, but he had one secret onscreen partner unbeknownst to fans in another film--himself.

The British hunk made the startling confession in the September 2013 issue of Germany Interview magazine.

Pattinson said he masturbated for his love scene in 2008's Little Ashes because faking it "just doesn't work," he said.

"So I pleasured myself in front of the camera," he said. "My orgasm face is recorded for eternity."

"If you Google something about long enough you will know everything there is to know about me," Pattinson also said to Germany's Interview magazine, "what I eat, what my poop looks like, with whom I'm sleeping, even what I look like when I masturbate..."

After he filmed the sex scene in an indie film, Pattinson considered quitting acting.

"I once decided to quit acting; it was when I did Little Ashes," he explained. "I played Salvador Dali and had to do a lot of scenes where I was naked, and I also had to masturbate. I mean really. A couple of days later, I was given the offer to do Twilight."

He also said he an awkward moment during the filming of Little Ashes--another actor was in the nude around him and it made him feel uncomfortable.

"The Dali production was the worst, it was mortifying," Pattinson also confessed. "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."
