Sienna Miller refuses to weigh herself. The stunning actress - famed for her svelte figure - doesn't own a pair of scales because she doesn't want to constantly worry about her weight.
She said: "I don't have scales in my house. Is that bad? If they're in a hotel room I'll go, 'Ooh', but they all say different things. Some of them will say I'm 5lbs heavier or 5lbs lighter so I don't believe them."
"There's a big pressure on women to look a certain way and it consumes people, and I don't think that's a healthy thing."
Sienna recently revealed she got in shape to play villainess The Baroness in "G.I. Joe: The Rise of Cobra."
The 27-year-old actress underwent six weeks of intense fighting and martial arts classes before starring in the action movie, and admits she was "reluctant" to exercise.
She said: "I had to get fit for the first time in my life, so that was entertaining. I was very reluctant, being English."
"I'm a good little scrapper now. I just couldn't believe it. I'd be like, 'Oh my goodness, I've got a muscle', but it's all gone to pot now."
