Celebrities Ashton Kutcher and Demi Moore aren't afraid to use their fame to make a difference. The Twitter enthusiast called out sex traffickers and the johns that support underage prostitution at the premiere of Killers in Hollywood last night, hopefully giving pause to any red carpet gawkers who thought Demi Moore’s boytoy was totally into sex slaves. There’s no reason for desperate men to resort to horrifying criminal activity to meet attractive women, anyway—they can always go on one of Ashton’s reality shows!
