Britney Spears posed for a new Candie's ad and didn't want any retouching. When retouching was done she decided to release the unretouched photos herself. I think she looks great without retouching. Kudos to you, Britney!
Jessica Simpson posed for the cover and a photo spread in Marie Claire Magazine without makeup and zero retouching. "I don't have anything to prove anymore,” Simpson told the magazine. “What other people think of me is not my business.”
