High School Musical star Ashley Tisdale sent youngsters into a tizzy after performing a surprise concert at a primary school on Friday.

After the final school bell rang for the day, students at Steck Elementary in Aurora, Illinois were thrilled to see a giant white tent and a stage had been erected on the playground for a special after-school show.

The excited pupils began screaming and jostling for the best views as the Disney sensation took to the stage to sing her hits. And older kids from nearby high schools were even spotted lining up outside barricades and squealing with excitement as they tried to catch a glimpse of the star.

Envious teen Amanda McDonough said, "Of course we're fans. We've got her music in my iPod. But my brother, he's lucky; he gets to be in there."
