Sienna Who? SIENNA Miller continues to embarrass herself in Pennsylvania, where she's shooting "The Mysteries of Pittsburgh." Having apologized for referring to the city as "S - - - sburgh," she threw a fit Saturday night when she was thrown out of Penny Folino's Young's Tavern because she didn't have ID. "Sienna ripped off her hat and said, 'I am Sienna Miller. I am a famous actress!' " Folino told the Pittsburgh Post-Gazette. Miller, denied her vodka and tonic, stewed outside for 30 minutes. Bouncer Dan Kovacs said, "She was going crazy out there, stomping her feet." Said Folino: "No ID, no entry - I'm sorry, we can't bend the rules for anybody."
