Bite me.

That's the request made of Robert Pattinson by some Twilight fans, the New Moon star revealed last night on The Late Show with David Letterman.

"With the swine flu going around," Letterman warned Pattinson, biting people may not be such a good idea.

So does Robert Pattinson actually accept such requests?

"Well, it depends on your mood, really...," Pattinson said. "And it depends on what you want to get out of it at the end. There's variations of biting."

“That’s a very strange experience. Yeah, there are the mothers,” added Pattinson, “In addition to that there are a couple of more guys.”

“There was a guy, a kind of maybe 230 lb guy, he was at the premiere,” he revealed. “Kind-of Hispanic-looking, and he was asking me to bite him as well. So I did."

“And the surprising thing was I kind of liked it afterward. I’ve been out to dinner with him a couple times since,” Pattinson joked.

While Robert Pattinson was busy chatting up David Letterman, his New Moon co-star Kristen Stewart appeared on Late Night with Jimmy Fallon.

New Moon, starring Kristen Stewart, Robert Pattinson, and Taylor Lautner opens nationwide tomorrow, Friday November 20th.
