Few stars will admit to it, but Sienna Miller has - most photos of her have been airbrushed to give her a more flattering appearance.

"Let's face it," said Sienna, "my so-called fabulous shape is the result of very clever airbrushing - I have small boobs and cellulite."

The 25-year old actress admits that it takes trick photography and some Photoshopping skills to smooth away her cellulite and increase her breast size. Sienna admits to eating whatever she wants, including greasy burgers and fries, and says that she doesn't exercise. But, she says: But I'd rather be lumpy and heavy than skinny and miserable."

Sienna is not the first celebrity who's admitted to airbrushed photos. Both Kiera Knightly and Kate Winslet have also shared their horror over their fixed up photos.
