An amusing video has emerged of popstar Kitty Brucknell falling on her back after attempting to stage-dive at a school concert in Hertfordshire, UK earlier this month.

The video, captured by Chauncy School student Amy Page, shows the X Factor series 8 semi-finalist hitting the assembly hall floor after attempting the rockstar manoeuvre.

Nearby students quickly helped the singer to her feet, as she continued her performance.

Brucknell, seeing the funny side of the accident, later wrote on Twitter: "attempting to crowd surf into a sea of year 7s and my butt hitting the floor has to be the funniest thing ever!"
