Actress Sienna Miller is quickly earning herself a reputation as Hollywood's messiest film star after leaving her FACTORY GIRL trailer in a bad state. Stylish Miller - who regularly tops best dressed lists - is less careful about domestic appearances and admits her movie dressing room disgusted co-stars and crew alike. She says, "I am a bit messy, I admit it. You'll usually find a few cigarettes in there and dirty socks. "I even stole someone's dog for company." Miller plays artist Andy Warhol's muse Edie Sedgwick in the George Hickenlooper movie.
