Britney Spears has kicked off her Las Vegas residency at Planet Hollywood and now that it’s in full swing, footage from fans has been surfacing across social media platforms. One fan caught Spears in the midst of a wardrobe malfunction, during which the singer almost lost her dress.

Spears was performing “Circus,” wearing a black and white striped and gold glitter sequined corset, when it suddenly came undone. She was dancing and spinning around, which exposed her bare back for a split second.

According to E! Online, a fan posted an Instagram video of the moment the dress flew open and Spears was overcome with a look of panic. However, one of her back-up dancers saved the day and quickly zipped it up for her before she showed the entire audience her naked body.

As he was working on getting the costume back in one piece, Spears attempted to continue dancing.

The fan wrote as a caption, “’Circus’ when her dress almost came off #britneyspears#britneyspearsconcert#vegas#lasvegas#dressmalgunction#singer#whathappensinvegasstaysinvegas.”
