Oops! Britney Spears Has Costume Malfunction—The Shocking Thing She Does To Fix It On Stage

The perky 33-year-old singer was getting her dance and sing on during her Piece of Me residency show in Las Vegas on Oct. 17, when smack in the middle of performing her hit "3", the zipper ripped wide open on the back of her costume!

Not only did the "Stronger" singer's costume pop completely open, it unzipped all the way down to her tailbone. And like a pro, Britney kept it moving, motioning just once for a dancer to come over and try to zip her back up.

But it turned into a slew of failed attempts, by numerous members of her dance troupe—many of whom took turns following her around, trying to pull her ensemble together, as she shimmied and shook, sang, dipped and turned—never once pressing pause on her flawlessly, executed choreography.

At the end of the song, the cheeky entertainer even turned her back to the audience, exposing her costume in all its ripped glory for everyone to see, as though the mishap were a part of the show.

The "Toxic" crooner has been wowing fans several times a week, ever since she began her residency at Planet Hollywood in Las Vegas almost two years ago. And this past September, the hot mama to cuties Sean Preston, 9, and Jayden James, 8, announced that she would be extending her run for another two years. Looks like she's gonna need alot of thread!
