"I mean you know they seem pretty excited about whatever. I'd like my fans to know that Cinnamon toast crunch only has 30 calories a bowl in it," he joked, referring to the box of cereal he had been handed as a gift for appearing on the show and partly an homage to the ice cream he ate on "The Daily Show" earlier this week.
Then he elaborated a bit more on celebrity life. "It's a different thing. You go into it to do movies," he said. "I've never been interested in trying to sell my personal life and that's really the only reason people bring it up. The reason why you go on TV is to promote movies. That's the only way to do it."
Pattinson went on to elaborate on celebrity life without ever addressing the elephant in the room.
"I think if you start getting used to [celebrity life], you start going crazy," he said. "It's nice. It's like being on the craziest theme park ride you've been on. It's totally exciting but eventually at some point you have to have a break."
Then the conversation started to veer back into the world of David Cronenberg's "Cosmopolis," which opens in limited released this Friday. After a clip is played where co-star Paul Giamatti points out that he can score more girls than Pattinson, the British heartthrob joked, "He does. If you go to Brooklyn Heights Paul Giammati is."
Pattinson then opened up about portraying 28-year-old business magnate Erick Packer, who watches his empire fall apart around him. "I always found this connection with the idea of finding it difficult to live in the present," he said. "It's funny it exasperates it being an actor. You actually have to focus on it, trying to exist in a contemporary way. I always feel like I was kind of living in the future. That's a lot of what Eric Packer's problem is. He feels like he's living in the future. He's not really being able to totally feel. It's funny. There's a lot of similarities to an actor's life.
"If you took the lives of people who controlled billions of dollars on the front page of every single paper, I think the world would be a better place," he said of real-life folks like Packer. "If you took away publicists and things, and people spoke for themselves, then they'd have to be responsible for their words."
Pattinson will be dishing more about the flick when he sits down with MTV News on Thursday for "MTV First: Robert Pattinson." Fans can tune in to hear what the "Twilight" star has to say when it all goes down at 7:49 p.m. ET on MTV and MTV.com.
