Sienna Miller: Post-Theater Clubbing

Sienna Miller drops by The Box Club with some friends on Thursday night (March 17) in Soho, London.

The 29-year-old actress headed to the club after finishing another performance of her latest play, Flare Path at the Haymarket Theatre Royal.

Sienna plays a married actress involved in a love triangle in the new Royal Air Force drama. The new play also stars Resident Evil‘s James Purefoy.

FYI: Sienna is wearing a Burberry leather jacket and carrying a Prada mandarino and nero madras leather bag from the Spring Summer 2011 collection. Her jeans and t-shirt are both by TwentyTwelve!
