Oh God ladies, this is super awkward.

Britney Spears was performing onstage during her Piece Of Me residency show in Las Vegas last week when she suffered QUITE the wardrobe/hair malfunction.

The singer, who is currently sporting a sleek blond bob, wears long hair extensions for the show – but her stylist clearly didn't clip them in tightly enough.

The 33-year-old was singing Do Somethin' when a large chunk of hair fell from the back of her head and swung for a few seconds before falling to the floor.

Ever the professional, Britney carried on as if nothing had happened – or she just didn't notice.

Either way, the whole thing would have blown over if a fan hadn't caught the episode on camera for us all to watch on repeat:

Britney launched her Piece of Me show back in December 2013 and has been performing three nights every week since then.

This is not the first on-stage embarrassment that poor Brit has suffered during her Vegas run – early on in the residency her costume's zip opened during a song, completely exposing her back.

Hopefully the hair extension debacle was the last of the malfunctions for a while!
