No matter what you think of actress Sienna Miller, she's generated enormous celebrity buzz since coming here to film "The Mysteries of Pittsburgh."

Her actions, real and alleged, have become fodder for news Web sites and celebrity blogs across the globe:

"Sienna Gets Narky" trumpets a headline in Britain's Sky News.

"Sienna's Temper Tantrum" reads Australia's Daily Telegraph.

"Miller Rejected From Bar" states the San Francisco Chronicle.

"Sienna Stopped at Club for ID" writes Tonight, a South African entertainment guide.

"Sienna Miller Denies Having Temper Tantrum" blares People.

"Sienna Miller Apologizes to Pittsburgh" declares the China Daily.

If Pittsburghers weren't quite sure who Miller was before she visited the Steel City, they know who she is now.
