Robert Pattinson talks on having underwear issues on the set of the new Twilight movie.  Only one pair left and they were Ellen underwear of course and the producers think that there is some sort of conspiracy when they show up in every shot due to not fitting quite right.

X17 - "I was doing the last Twilight movie and I only had one pair left and they were those ones [the "Ellen" underwear]," Rob said. "We were doing this big fight screen and for some reason I think the shape of my body, my back is too long or something. So my *ss is constantly hanging out ... Every single shot we were doing this big fight and every shot has these Ellen underpants. It came to a point where producers are calling up my agent going, I don't know what he is up to but I don't like it."
