OMG! Demi Lovato falls to the floor during a stage performance!

Spare some sympathy for a bruised Demi Lovato after she suffered a Naomi Campbell moment in front of thousands of fans at the weekend.

The Disney star was performing in the US when she took a tumble to the floor descending stairs onstage. Luckily Demi saw the funny side and burst into giggles apologising for the blunder to the crowd. Bless.

One big, hearty cheer for YouTube for capturing the vid below and just try to not laugh! Watch it now...

Ouch, that's gotta hurt. Plasters, anyone?
