Britney Spears powered through a major wardrobe malfunction on Friday while performing "3" during her Piece of Me show in Las Vegas. Wearing an ultra-sheer, black one-piece, Spears kept on dancing even as her costume's zipper split all the way down her back. A few backup dancers attempted to lend a hand, but Spears seemed much more interested in keeping up with her choreography! See the performance in the video below.
With that flawless physique, Spears didn't seem too worried about showing off her toned back and peek-a-boo tattoo. Luckily, the front of her costume managed to stay securely in place until the end of the performance.
