Actress thinks she has a large backside

Sienna Miller insists her body is far from perfect.

The G.I. Joe star, 28, thinks her bottom is on the big side.

‘My top half is looking pretty good at the moment,’ she says. ‘But you should see my bum.

‘It wobbles when I walk. Seriously, I have a lardy arse.

‘I have days when I wake up, look in the mirror and go: “Yuk”.

Sienna admits she even has some orange peel skin.

‘If I do a nude scene they put make-up all over your body so it looks like you have a nice bum,’ she tells OK!

‘When there is all that make-up on you don’t see the stretchmarks that all us girls have.

‘But I’m fine with that and cellulite – it’s normal.’
