Fanbolt have posted their interview with Peter Facinelli:

Did you actually bite Rob? And was that weird at all for you?

Peter: I did sink my teeth into Robert, but it wasn’t weird. I was coming from a place of a vampire. It wasn’t like I was kissing his neck (laughs). Rob and I actually talked about that scene in particular. How it happened, and how it went down. I thought it was interesting to whisper something to him before, and in the movie they kept that… and then I bit him. And no one will ever know what I whispered to him which I thought was really cool. It’s between me and Rob.
