Katy Perry Videos: Hot performance at AMA 201: Katy Perry has already revealed her inspiration for her latest single, "Firework." But the pop star took the track a step further during a high-energy performance that included sparklers at the American Music Awards.

As the number began, a children's choir crooned the chorus of the empowering tune. It was Perry, however, who really made an entrance, descending from a star suspended from the ceiling. Dressed in a furry red dress (one she later ripped off to reveal another ensemble), the "Teenage Dream" singer walked to the front of the stage as the choir dispersed and backup dancers joined her onstage. Meanwhile, backdrop screens showed a slew of fireworks as Perry's dancers shot sparklers through handheld gadgets.

The pop star ended the visual light-fest on a high note, singing the last few notes of "Firework" while her dancers lifted her high up in the air. Perry is also nominated in multiple AMA categories, including Favorite Female Artist, Favorite Album and Artist of the Year.

The newly married Mrs. Brand teased the performance via Twitter a few days ago, writing, "Just finished AMA rehearsal... I am so excited about this remix performance. It's going to be a mixture of adorable & gorgeous. #AMA'S."

Perry spoke to MTV News about writing the inspirational track, her third single from Teenage Dream. "I think that's why I wrote it, is because I really believe in people and I believe that people have a spark to be a firework," she said. "It's just up to them, and a lot of times it's only us that's standing in the way of reaching our goals, fulfilling our destinies, being the best version of who we possibly can be, so that's why I wrote it."
