Ashton Kutcher, 29, left a phone in the back of a taxi while holidaying in Spain with 44-year-old Demi Moore , only for it to be found by a man who's now looking to sell the intimate photographs for $1.13 million.

"In some of the 35 pictures, Demi lies sprawled naked on a bed," says a source. Other revealing photos show the actress clad in a sexy black bra and propped up against a pillow.

"When Demi and Ashton got word that someone had their racy pictures, they freaked out," claims another source close to the couple. "Not only are they embarrassed, they're angry."
