Scout Willis showed a never-before-seen sultry side to her this week when she posed flashing her naked ass in chaps, and RadarOnline.com has exclusive details on the sexy photo shoot.

Photographer Magda Wosinska told RadarOnline.com in an exclusive interview that Bruce Willis and Demi Moore's middle daughter had no reservations about baring her behind on the back of a motorcycle.

"She is down for it all. It's great!" Wosinska revealed, adding that Scout was, "stoked" to take part in the shoot, where the 20-year-old can been seen posing bare ass in chaps for an artistic series of black and white images on StyleLikeU.com.
