Sienna Miller is Groucho Grouchy

Sienna Miller leaves the Groucho club in a plaid dress in London, England on Thursday (June 11).

The 27-year-old hottie plays The Baroness in the upcoming film, G.I. Joe: Rise of Cobra. An action figure was created for Sienna and she commented on the process, saying, “I got measured in this pod so the doll is exactly to scale – every nook and cranny. They showed me my bald head before it was painted on and it was me! That was weird!”

The film opens this summer on August 7th across the country.
