Katy begins the performance singing "Roar," the hit single off her latest album, Prism. She wore the clothing equivalent of a flame. She then performed "Dark Horse,"on a stage that looked like a chess board. Then Kravitz showed up to help Perry with "I Kissed A Girl."
Missy Elliott's "surprise" performance was next. She performed three songs, including "Get Ur Freak On" and "Work It," making the crowd pumping.
Perry closed out her halftime show with a rendition of her hit "Firework," which included her flying above the crowd on a star.
