Sienna Miller has revealed that her body isn’t as perfectly smooth and flawless as it appears to be in her nude scenes in Factory Girl.

She told Closer magazine recently: “They spray make-up all over your body so you don’t see the stretch marks that we girls all have.”

She added that she doesn’t maintain a healthy lifestyle and one day it’ll catch up with her: “I don’t eat salads and I don’t drink skinny coffee.”

“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!”
