Her mom posed naked and pregnant on the cover of Vanity Fair, and her dad scaled buildings shooting machine guns in Die Hard, but Scout Willis has proved she is the real bad-ass in the family with a provocative new photo shoot.

Bruce Willis and Demi Moore's 20-year-old daughter can been seen posing bare ass in chaps on the back of a motorcycle for an artistic series of black and white images on StyleLikeU.com, which was previewed on Wednesday on Stylecaster.com.
