The 35-year-old Piece Of Me singer was in the middle of performing when a man jumped on stage.

Her security team and even her backing dancers swung into action almost immediately, slamming the man to the ground.

In video of the attempted attack obtaned by TMZ you can hear Britney ask her team if everything is 'OK'.

Her knees then appear to buckle as she grips onto the arm of a security guard and asks: 'He's got a gun?"

Apparently that's when he jumped onto the stage.

He's since been arrested for tresspassing.
