Sienna Denies Her Temper Tantrum

Sienna Miller is denying that she recently freaked out at a Pittsburgh bar. Her London rep, Clara Parkes, told People that the claim is simply untrue. "

These people are utter fantasists. We have 10 witnesses, including local Pittsburgh people, who can vouch that Sienna never reacted this way and left the bar quietly. It is utter rubbish."

Parkes also maintains that Sienna, who is filming The Mysteries of Pittsburgh while in the city, that Miller is denying she "in any way acted in an inappropriated manner." You can learn more about Sienna Pittsburgh drama by clicking here.
