Britney Spears almost uncovered her breasts during an unlucky on-stage attire malfunction on Saturday night.

The 34-year-old Pop singer endured the event while performing the hit "I Love Rock 'N' Roll" when the strap to her top loosened around her neck and fell.

Britney instantly covered herself with her left hand. While, two of her male dancers frantically tried to fasten the top but their efforts were pinched as it soon fell open again.

After changeover into her hit "Gimme More," a backup dancer charitably took off his collared colored shirt and extened it to the star to put over her bra and cut-off vest. So, she quickly put it on and borne on with the routine as usual because, if there's something a lifetime experience of performing has trained her, it's that the show must go on.

Nothing can stop her moment, as all eyes on her while still performing for thousands of fans. Britney, who is no stranger to flashing the flesh, was performing her Piece Of Me show at The Axis inside the Planet Hollywood Resort & Casino. The singer managed it like a pro and didn't let it discontinue her killer production.

Britney recently caused argument after an unseen version of her video to "Make Me" leaked online. Another video revealed the sexy singer begin with intended to go X-rated in a way you've never seen before.

This isn't the first time she's faced a wardrobe glitch in Las Vegas. Just a week earlier, Spears was performing her usual for "3" in a black sheer blouse when it suddenly unzipped and stuck. Though several backup dancers tried to pull the suit sane, no one could get the costume to fasten back up, but she carried on without reluctance.

Rather, Spears finished the performance with her entire back open-because no wardrobe malfunction will ever get Britney to fail.
