Jessica Simpson Jessica Simpson

Jessica Simpson is going for an all-natural look in a new photo spread for Marie Claire magazine.

Simpson appears on the cover of the mag's May issue, which features cover lines that claim that the singer is not wearing make-up and that the cover image was not digitally retouched.

Jessica Simpson: "I don't want people to know how I am in bed" 

Simpson also served as the guest beauty editor for the issue, espousing a more minimalist beauty regimen, including air-drying her hair. "I don't have anything to prove anymore. What other people think of me is not my business," she told the magazine. She also said she likes "bed head," so much so that if she's in a hang-out mood, she won't even bother to wash her hair. "I'll wait until it smells," she said.

Do you believe the mag's no-makeup claim? And what do you think of Simpson's stripped-down look?
