Sienna Miller looks quite pleased with her performance after leaving the Theatre Royal Haymarket in London.

The 29-year-old actress is starring in the West End production of Flare Path, where she plays Patricia Graham, a stage actress torn between her brave pilot husband and a washed-up Hollywood film star who wants her to get a divorce.

The newly single lady recently opened up to U.K.’s Guardian on her split with Jude Law, revealing, “We weren’t [re-engaged]. And I think this happens in everyone’s lives: you get back together, you try and make it work, and it doesn’t. It’s not acrimonious, it had run its course."

Path will have its official opening Thursday, March 10, and will run through June 2011.
