Justin Bieber & Friend Bite Topless Stripper's Nipples

Justin Bieber, once considered an innocent young man adored by tweens everywhere, has certainly become something else. A photo has emerged of the Biebs and his buddy Khalil Sharieff double-teaming a stripper's boobs with their mouths during a recent party.

Sources tell TMZ that the stripper was hired to perform for Bieber and his friends during a party at an L.A. recording studio. Sources also say the stripper, who arrived equipped with giant fake breasts and Playboy bunny tattoo, looked old enough to be Justin's mother.
