Star says she's far from perfect

She has a body most of us would kill for.

But it seems even Sienna Miller likes to have a bit of a whinge about her imperfections.

The 25-year-old actress, who strips off for her new film Factory Girl, admits her body only appears flawless on screen because of make-up and clever camera work.

‘They spray make-up all over your body so you don’t see the stretch marks that we girls all have,’ she admits.

But it is a comfort to know that Sienna is happy with her weight and refuses to go on a diet.

‘I don’t eat salads and I don’t drink skinny coffee,’ she says. ‘I do run around a lot but I’m not healthy. One day I’ll wake up and my bum will be on the floor.’

We seriously doubt it.
