Britney Spears’ backup dancers and security guards tackled a fan that bum-rushed the stage at her Piece of Me residency in Las Vegas at the Planet Hollywood Resort & Casino on Wednesday, August 9.

The scary moment was caught on camera by concertgoers who later posted their videos to social media.

Spears was performing "(You Drive Me) Crazy” and appeared to be unaware that someone had jumped on the stage as she continued interacting with the crowd, asking the audience, “Are you guys having fun?”

Security then surrounded Spears who realized what was happening and was taken aback. 

“Is everything okay? What’s going on?” Spears could be heard asking as the microphone was still on. She was then quickly rushed off the stage.
