British model/actress Sienna Miller was brought down to earth on Saturday when security guards at a Pennsylvania bar refused to let her drink in the establishment. Bouncers at Young's Tavern in Pittsburgh were unconvinced the 24-year-old blonde was old enough to drink in the bar - despite being three years over the legal drinking age of 21.

Tavern owner Penny Folino tell the Pittsburgh Post-Gazette newspaper, "Sienna ripped off her hat and said, 'I am Sienna Miller. I am a famous actress!'" Miller attempted to enter the drinking spot for 30 minutes, but eventually gave up.

Security member Dan Kovacs says, "She was going crazy out there, stomping her feet. Folino said, 'No ID, no entry - I'm sorry, we can't bend the rules for anybody.'"

Miller isn't very popular with residents of Pittsburgh after referring to the city as "s**tsburgh" in a recent interview with Rolling Stone magazine.
