DEMI LOVATO SURPRISES SCHOOL CHILDREN WITH GIG

Demi Lovato stunned young students at a Utah school on Monday (17May10) by turning up for a surprise gig.

The Disney sensation was billed only as a "special guest" who would be performing at Oak Hollow Elementary School in Draper, Utah after an eight-year-old student won a radio contest.

The children were delighted when Demi Lovato stepped onstage - and the teen sensation was thrilled by her reception.

In a post on her Twitter.com page after the gig, she wrote, "Just shut down Oak Hollow elementary school... WHAATT?!! Hahahaha."
