Wyclef Jean and Lil Buck turned a black tie affair into a straight up dance-off inside NYC's Guggenheim Museum.
The star-studded Hublot after-party went down Tuesday night and at first, 46-year-old Wyclef held his own in the middle of the fancy event -- but Buck shut it down with his signature move. After all, the guy's a master contortionist, who was even scouted by Madonna for her dance crew.
Wyclef didn't go down easily though -- check out his final move. We're not sure if he nailed it, or just nailed his spine.
