Scout Willis' bare (blurred, by ABCNews.com) bottom.

Like mother, like daughter. At the tender age of 20, Scout Willis is already mimicking the body-baring ways of her 49-year-old mother, Demi Moore.

In a new editorial for the website StyleLikeU (a preview was posted Wednesday at StyleCaster.com), Willis poses in a pair of bottomless chaps and flashes her full, naked rear end while sitting on the back of a motorcycle. She gives the finger to the camera in another shot that shows her backside in profile. She wears little more than a coat or a blanket in many of the other photographs.

The Brown University student is ahead of the game. Moore posed nude for the August 1991 issue of Vanity Fair when she was 28 and seven months pregnant with Willis. How's that for a coincidence? Another one: StyleCaster.com's photo gallery of Willis is sponsored by Nikon, whose celebrity endorser is Ashton Kutcher, Moore's soon to be third ex-husband.
