Britney Spears gives audience a 'piece of me' with latest wardrobe malfunction

Oops, she did it again.

Britney Spears has suffered another wardrobe malfunction at her latest Las Vegas Piece of Me show at The Axis, Planet Hollywood. But if you ask the pop queen herself, there's no "suffering" going on at all.

In fact, the 35-year-old seemed totally oblivious to the fact that her breast went peek-a-boo as her sparkly leotard didn't quite do its job. Oh baby, baby, how was she supposed to know?

An eagle-eyed fan posted the moment, during her performance of her hit 'Work Bitch', on Twitter, where it was rapturously received by her devotees.

"Level of not giving a f---: Britney performing with her boobs out," wrote @godneybjs.

Britney is no stranger to an onstage outfit ordeal, of course. Last October, she recovered like a pro when her bra top came undone onstage in Vegas. And the October before that, her bodysuit zip split open mid-performance.

Each and every time, she handles it with a happy-go-lucky, get-on-with-it attitude. Nothing toxic about that!

However, some fans have lamented that her latest nipple slip is stealing attention away from her charity work.

"Britney is literally helping to build a cancer facility and all y'all care about is her boob coming out," tweeted @gimmeasign.

Britney thanked fans yesterday for donating and raising funds for the Nevada Childhood Cancer Foundation's new centre. The singer donated $200k to the foundation last October, and raised $550k during her Piece of Me charity cycle.
