The pop star, 33, was performing her 2009 single, "3" when the zipper on the back of her outfit suddenly split open.
The singer motioned to her backup dancers to zip her zipper back up, but because the choreography called for her dancing across the stage, they were at first unsuccessful.
Just like a pro, the "Stronger" songstress decided to turn her open zipper into part of her sexy choreography routine, continuing to sing and dance while her back was exposed. When the song was done, Spears rushed offstage, presumably to fix her outfit.
