Rob Pattinson chatted with Ryan Seacrest on KIIS FM today about living "in this Twilight bubble... I'm just constantly going from city to city and people scream at you. I feel like it's my job."

And what's his reaction to so many girls screaming, after being camped out waiting to see him?

"Uh, hey, do I have to get naked or something?"

Aw, he's funny, too! Pattinson - who's "signed on for the next two" films - claims that he's "not really an actor... I don't really know what I'm doing!"

Ryan then brings up Rob's hair - especially the "volume" of it - and offers to pay him to shave his head. "If you wait a few more months," Rob answers, "I'm doing it anyway." He also mentions that Ellen [DeGeneres] wanted to wash his hair, but he said "she could only wash it if we had a bath together."

What about the question that's on everybody's mind - Is Rob single?

"Yes, I am," he replies. (Woo-hoo!) And what kind of girl does he like? "I don't know anymore."

Here's your chance, ladies! Just watch out for any females you spot with Rob while he promotes Twilight... apparently the PR company makes sure there's always girls to "just follow me around."

Doesn't Pattinson already have enough fans to do that for real?!?
