Robert Pattinson may be a global heartthrob, but when it comes to his own romantic exploits, the Twilight star admits he can be a bit wimpy. “I can’t think of a single romantic thing that I’ve ever done,” Pattinson said while promoting the latest installment of the vampire series, New Moon, in Los Angeles Nov. 6.

“I would never serenade someone to be romantic – you have to have so much balls to do that. I put a flower in someone’s locker when I was 15 years old, this girl called Maria. She thought that it was someone else and the other guy claimed it as well, which is great.”

Despite his claims, Pattinson, 23, says he is a big believer in onscreen romance and balks at the common notion that it’s for ladies only. “It’s like saying guys can’t appreciate romance,” he says. “I’ve watched Titanic and I didn’t think, ‘Oh, this is a girl’s film.’” Similarly, he says, “I felt like the storyline in New Moon is very heartbreaking and true. I didn’t think I was doing something just for the sake of romance.” That said, are there any real similarities between Pattinson – rumored to be dating costar Kristin Stewart – and his tortured alter ego, Edward?

“I get quite obsessive about things, and possessive as well,” says the star. “I have very, very specific ideas about how I want to do my work and how I want to be perceived, to the point of ridiculousness sometimes.”

“I don’t listen to anyone else,” he says. “That’s why I don’t have a publicist – I can’t stand it if someone’s trying to tell me to do something which might be a mistake.”
