(USA TODAY) -- It was just the second night of her Las Vegas residency show when - oops! -
Sorry, gang, this mishap involved her back.
Theentire back of her corset-type costume fell open during her Dec.30performance, showing her bare back. She kept right on dancing and muchmore could have been revealed, but it all managed to stay together.
Twoof the pop star's backup dancers, quickly tried to help zip and clipthe glittery top back together while Brit kept right on singing her hitsong Circus.
It all seems to have earned her the title of Last Celebrity Malfunction of 2013! Congrats, Brit!
