Britney Spears suffers wardrobe malfunction as her boob falls out during live performance

The singer has one of the most successful residencies in Las Vegas, but it all went a little wrong last night. The legendary icon, who released her latest album Glory to rave reviews last year, hit the stage last night in Sin City to a sold-out crowd.

During a performance of one of her string of smash hits, the star unfortunately had a major wardrobe malfunction that left her exposed.

As she pulled off a tricky dance move, the star's boob popped out of her top and the moment was caught by an eagle-eyed fan.
