Video: Fans pounce on Demi Lovato

Poor Demi Lovato was pounced on by fans during a recent concert.

The singer was playing a concert in Paraguay when fans got up on stage with her. Security acted fast, whisking Demi away and ushering the fans back into the crowd.

Ever the professional, Demi came back out almost straight away and told her fans to try and chill so that the show could carry on.
