If you didn't think backpack kid's dance move could look sexy, allow J Lo to convince you otherwise. She and Jimmy Fallon took turns dancing very fast to "the least danceable" slow songs of the '70's for a segment on the The Tonight Show Starring Jimmy Fallon. Of course, the super competitive singer had to get the rules spot on, to give her the best chance at winning. But as the duo started things off with what looks like an inside joke, J Lo hilariously ended up flipping Jimmy off.
Though she might have been apprehensive at first, the 48-year-old star looked incredible wearing a red sequinned dress on the dance floor, pulling off the moves in style. After both put on a pretty awesome show, they finished with an epic "backpack kid" interpretation dance to "Reunited," by Peaches and Herb. While J Lo nailed the move, Jimmy may have a little more practice to do before he becomes a master of the art. Watch the full video above.
