London: Sienna Miller has thrilled fans by stripping off for a fruity film role.

The 25-year-old actress wore nothing except a garland of flowers in her hair while shooting scenes for her new movie ‘Hippie Hippie Shake,’ in a garden in West London’s trendy Notting Hill Gate.

“She sat on the grass with the flowers in the hair and danced on the grass waving her hands. She looked simply gorgeous,” The Sun quoted an onlooker, as saying.

In the movie, which centres on the infamous Oz magazine obscenity trial of the 1960s, Miller plays artist Louise Ferrier, girlfriend of Richard Neville who edited the underground mag.

The movie, wherein Cillian Murphy will play Neville, is due to be out next year. (With Inputs from ANI)
