You never know what’s going to happen at a Britney Spears concert, but this is one surprise even the songstress didn’t see coming.

Spears, 33, was busting out signature moves to her hit “3” at her Las Vegas show on Friday when her sexy costume broke open and revealed her lower back.

It didn’t take long for two thoughtful male dancers to rush to her side and offer some help. Try as they might, the guys weren’t able to fix the situation. None of it stopped Spears, though – the “Work Bitch” singer kept on moving and reminded everyone she’s a consummate showwoman.

The costume is a recent addition to her massively successful Piece of Me residency at Planet Hollywood on the Vegas strip, which she kicked off in 2013 and extended for two more years in September.

If the semi-transparent body suit looks familiar, you might recall how she debuted the outfit while performing “Pretty Girls” with Iggy Azalea at the Billboard Music Awards in May.

When she hasn’t been busy stunning on stage lately, Spears has grabbed headlines with everything from her cute moments on the set of Jane the Virgin to a picture-perfect night out with Kate Hudson.
