Britney Spears performs at her "Britney: Piece Of Me" show at Planet Hollywood Casino Resort on March 4, 2015 in Las Vegas, Nevada.

Nothing is going to get Britney Spears to stop dancing -- even a rogue zipper.

During the singer's Piece of Me show in Las Vegas over the weekend, Spears suffered some kind of wardrobe malfunction on the back of her sheer outfit.

Many of her dancers were on it, quickly trying to assist her, but Spears kept up her choreography, outfit falling apart or not. Isn't she lucky?

Watch her performance of "3" below.
