She strips off for new movie

Sienna Miller has been snapped starkers sitting in a garden in London.

She was filming scenes for her new 60s-style film Hippie Hippie Shake in which she plays a London socialite.

Sienna, 25, faced the cameras in Notting Hill wearing nothing but a floral garland on her head.

‘She sat on the grass with the flowers in her hair,’ an onlooker tells The Sun.

‘And danced on the grass waving her hands.

‘She looked simply gorgeous.’
