Britney Spears almost exposed her breasts during an unfortunate on-stage wardrobe malfunction on Saturday night.

The 34-year-old singer suffered the mishap while performing the hit “I Love Rock ‘N’ Roll“ when the strap to her top unclasped around her neck and fell down.

Britney immediately covered herself with her left hand.

Two of her male dancers desperately tried to fasten the top but their efforts were wasted as it soon fell open again.

Like a true gentleman, one of the dancers later removed their flannel shirt which the singer put on – all while still performing to her thousands of fans.
