Jessica Simpson graces the May cover of Marie Claire (on newsstands April 13) with absolutely no makeup or retouching, says the mag's publicist.

She went au naturel to promote her initiative, "A Beautiful Me" - a program she is launching to encourage young women to love themselves and feel comfortable in their own skin. The program launches at the close of her VH 1 series in May.

Says Jess: "I don't have anything to prove anymore. What other people think of me is not my business."
