Britney uncovered! Star's sheer catsuit rips onstage leaving entire back exposed

Britney Spears might want to consider investing some of the millions she's raking in from her standing Las Vegas engagement on sturdier stagewear.

The 33-year-old singer was performing the hit '3' during her "Piece of Me" Vegas show when the zipper on the back of her sheer catsuit ripped, leaving her entire back – and then some – exposed.

Watch the video above to see Brit's wardrobe malfunction followed by several unsuccessful attempts by her back-up dancers to fix it.

No worries, though. The moment was far less embarrassing for Britney than it was for her clumsy dancers, who looked ridiculous trying to repair the damage as their boss continued to dance.

As for Britney's flipside, it's impressively well-toned. Meanwhile, the unintentional exposure added some risky edge to the outfit. A redesign might actually be in order.
