MTV: Meanwhile Robert Pattinson has been describing the vampire sex in the film as "ridiculous" in recent interviews.
(Kate: Well we all know that's NOT actually what he said and thankfully so does Stephenie)
Meyer: Yeah I saw that. I think he was talking about how it was so hard to keep a straight face [during that scene]. (Kate: EXACTLY) For the actors, there are 40 people in the room and most of them are inches away from you. It's a kind of awkward menage-a-forty going on. I think when you see the scene it's a testament to their acting ability that you don't see any of that in that moment at all.
For Stephenie's full interview (which includes her talking about the "supposed" extra scene) head over to MTV
