Sienna Miller is a Groucho Girl

Sienna Miller (in Genetic Denim skinny jeans) and a mystery male leave London’s Groucho Club around two in the morning on Thursday (January 15). The 27-year-old British actress was seen heading to Jerry’s Club and left there around 3:30 a.m. through the side door to avoid photographers.

Sienna was reportedly dumped from the upcoming Robin Hood rename “because she’d make co-star Russell Crowe look old and fat.”

An insider told the New York Post, “It is a mess. Russell never lost the weight he put on for Body Of Lies and so the love scenes between him and Sienna would have been laughable. He’s so old and fat and she’s so young and gorgeous. [Producers are] looking for an older, plumper actress to play the role so Crowe doesn’t look like a paunchy grandpa. Someone in her late 30s or early 40s”.’
