Britney Spears suffered a wardrobe malfunction while performing during her Las Vegas show.

The 42-year-old pop star was belting out her 2009 single 3 in a revealing black mesh unitard with strategically placed pleather patches.

Britney was about one-third into the performance when her back zipper broke and split open.

The singer never skipped a beat as she motioned for her backup dancers to help.

Several dancers took stabs at zipping her up but couldn’t manage it.

Britney eventually let it go and worked the wardrobe malfunction into her routine as she bared her back for the audience.
