HipHopHollywood convinced Channing Tatum to make his ass clap during an interview for Magic Mike in exchange for the interviewer’s favorite pair of hoop earring. It was worth it. According to her.
However, only Tatum did it. I hear McConaughey isn’t legally allowed to do it because when his ass cheeks clap, it sounds like sonic booms and LA is pretty strict with their noise ordinances.
