London: Popstar Katy Perry returned to her high school after a decade to play a free concert.
As the bell rang for the end of the day, students of Dos Pueblos high school rushed to their amphitheater where they were greeted by the `California Girls` hitmaker.
The outdoor stage was not like an ordinary school concert though, the 25-year-old`s platform was complete with drum risers, smoke machines and faux lollipop stage sets.
Perry began her show wearing a cheerleader`s outfit and later stripped off to reveal a latex mini dress, reported Daily Mail online.
Perry then broke into her superhit debut track `I Kissed A Girl`.
"I was on this very stage many a lunchtimes. I was such a showoff. There was a pumpkin pie-eating contest, which I won, and a freestyling contest that I lost. That was one of the saddest days of my life," said Perry about her days in high school.
