SIENNA MILLER - MILLER FAILED FILM WEIGHT CHALLENGE

MILLER FAILED FILM WEIGHT CHALLENGE

SIENNA MILLER was mocked by co-star GUY PEARCE on the set of FACTORY GIRL, because she failed to lose enough weight for the role. Pierce and Miller were given target weights by movie bosses for their roles as artist ANDY WARHOL and his muse EDIE SEDGWICK. The Australian slimmed down comfortably, but Miller struggled - and was handed the nicknamed "Little Fatty Edie". She says, "The awful thing was he was really disciplined about losing the weight and I wasn't. "I didn't want to. I love my food. I'm an energetic person but I don't work out and I do eat a lot. "It's quite funny that Andy was skinnier."
