SHAUN WHITE IN X-RATED PHOTO SCANDAL

A butt naked Shaun White smiled for the camera ... while messing around on a bed with a hot naked lady back in 2009 ... and now the X-rated photos are being shopped around town ... TMZ has learned.

Sources tell TMZ ... the photos were taken at a hotel party ... a short time before The Flying Tomato won a gold medal at the 2009 Winter X-Games for Superpipe (haha ... superpipe).
