Did Robert Pattinson Wear Ellen's Underwear in 'Breaking Dawn'?

Robert Pattinson confessed to Ellen DeGeneres that a gift she gave him ended up appearing in the last 'Twilight' film.

Ellen had given Rob a pair of "The Ellen DeGeneres' Show" underwear, and the 'Twilight' heartthrob tells Ellen, "I was doing the last 'Twilight' movie and I only had one pair [of underwear] left and they were [the 'Ellen' underwear]. We were doing this big fight scene 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."

Rob continues, "I genuinely think I have a few two many extra vertebra or something. 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."

Ellen replies, "Like there is some conspiracy theory of my underwear being in the movie or something."
