Britney Spears suffered a wardrobe malfunction during her concert at the Axis Planet Hollywood in Las Vegas Friday, E! News reported. The 33-year-old pop star took it in stride as she continued performing even though a broken zipper in the back of her catsuit left her back exposed.

Spears began her performance of her 2011 dance hit "3" with a countdown, according to fan-shot footage. She wore a skin-tight sheer and vinyl black catsuit, which showed off her toned legs and curves. She danced and slid across the stage on metal triangle structures, and many of her moves required her to kneel down on the ground.

At about one minute and 20 seconds into the song, Spears can be seen with her hand on her back, feeling for the zipper that popped, exposing her back. Multiple dancers attempted to help her with the closure with no luck, but Spears kept a smile on her face and didn't let the malfunction stop her from continuing her performance. At one point, Spears spun her back to the crowd, and the audience cheered.

The "Oops I Did It Again" singer has been performing in Las Vegas since 2013 when she signed a 2-year contract for $30 million, according to the Daily Mail. She announced last month via Twitter that she signed on for another two years for a reported $35 million.
