Sienna Miller News & Pictures

Factory Girl Sienna Miller will appear in the new issue of Life Magazine, and the actress finally dishes on how she was affected by the cheating of ex-BF Jude Law.

A New York Daily News insider reports that Sienna Miller and her co-star Hayden Christensen were actually having sex during the film’s signature steamy love scene.

Monday morning’s video footage of Diddy dropping Sienna Miller off at her New York City hotel isn’t the only survellience secured of the two stars partying while Diddy’s wifey is at home nursing twin girls.

A pantless Sienna Miller was visibly shaken when approached about her seemingly less than innocent relationship with Diddy at the New York City red carpet premiere of her flick Factory Girl on Monday night.

Actress Sienna Miller showed up at the New York premiere for Factory Girl in a sixties style mini-dress, but changed into a black top, black boots, accompanied by black tights for the afterparty.
