Robert Pattinson On Nightline: I'll Probably Die By Age 30 (VIDEO)

Robert Pattinson sat down for an interview with 'Nightline' that aired Monday night, and he opened up about fame, the extended foreplay in 'Twilight' and his secrecy about his relationship with Kristen Stewart.

"In logical terms, if you're just walking down the street and every single stranger on the street knew your business and came up and felt the need to comment on it, you'd just be like, 'Shut Up! I'm gonna kill you,'" he said. "It's exactly the same mentality... I don't really want to try to sell it either. Maybe if I was selling it, I'd talk about it more."

Pattinson also joked about expectations for an early death.

"I guess I just thought if too many good things happen, then you're gonna die at 30," he said. "I didn't want that to happen. Yeah, so probably, I'm going to die at 30. Actually, it's God saying, 'Hey, you shouldn't have asked for too much.'"
