Robert Pattinson doesn't seem to mind that fans go for pure vampire cliche and ask him to bite them. He isn't moody vamp Edward Cullen in real life, but the "New Moon" star is still willing to oblige them.

"There are some mothers, and then also there are a couple more guys from this sequel," he said on "The Late Show with David Letterman" on Wednesday night. "There was a guy, maybe a 230-pound guy who was at the premiere, kind of maybe Hispanic looking, and he was asking me to bite him as well.

"And so I did, and the surprising thing was, I kind of liked it afterwards," Pattinson joked. "And I've been out to dinner with him a couple of times."

When Letterman raised concerns about the health risks of biting strangers, Pattinson said he only does it if he's getting something out of it too. "Well, it depends on your mood, really," he laughed. "And it depends on what you want to get out of it. There's variations of biting."

Pattinson went on to explain how he ended up chomping on a small child. "That was before anyone had asked me to bite them at all. I just thought it was hilarious that someone had handed me this child to do whatever with," he said. "Initially, I just thought they were giving it to me. And somehow I ended up biting the baby on the head, and there was a photo of it afterwards."

Letterman then changed gears for a minute to ask Pattinson to confirm that he's dating Kristen Stewart. "I've been so, kind of, cryptically avoiding this question throughout the entire press tour ...," Pattinson trailed off uncomfortably.

"Oh, bite me," Letterman interrupted. "What do I care?"
