Jessica Simpson has appeared make-up free on the cover of Marie Claire magazine.

The 29-year-old star - who came under heavy criticism for gaining weight last year - did the cover shoot, which is also free from retouching, in an effort to challenge pre-conceived notions of beauty. It looks as if she actually brushed her teeth, too!

“I don’t have anything to prove anymore. What other people think of me is not my business.”

However, the sexy singer, who recently fronted The Price of Beauty - a documentary following Jessica as she tries bizarre beauty treatments across the world - did admit she would still get dressed up when she felt she wanted to: “If I’m in a mood to go out and feel hot and sexy, I want long hair that I can feel on my back. But I also like bed head.”

Recently Jessica confessed she has changed thanks to her acceptance of her body and looks. She said, “There’s always something that I’ve wanted to fix because there’s always somebody who looks better; that’s what we always compare ourselves to. So I think the journey really was finding what was beautiful inside of me and knowing that it’s unique and rare. And it was a very powerful journey. It has definitely changed my life.”
