Justin Bieber had another embarrassing on-stage incident after he fell down some stairs whilst performing.

The Canadian superstar recently entertained millions of fans across the world on the internet after video footage emerged of the singer throwing up on stage.

He later blamed the incident on a pre-show combination of pasta and milk.

Bieber has now been filmed falling down some stairs whilst performing with pop comrade Carly Rae Jepsen on Tuesday (October 16).

He was singing the track 'Beautiful' with Jepsen whilst playing in Canada before taking a tumble, with Jepsen on hand to help him back up.

British singer Olly Murs, meanwhile, set the benchmark for comedy stage falls this year after video footage showed the star launching head first down some stairs at GuilFest.
