Katy Perry performed her hit song 'Teenage Dream' during the Super Bowl halftime show, and did so with the help of some dancing sharks.
Perry has had nine No. 1 songs on the Billboard Hot 100 chart. Some of the pop star's most notable hits include "Firework," "Roar," "Dark Horse" and "California Gurls." Her 2010 album "Teenage Dream" had five No. 1 singles, tied with Michael Jackson's "Bad" for the most all-time.
Perry's most recent album was "Prism," which included the hits "Dark Horse," "Roar" and "Unconditionally."
The NFL officially announced in November that Perry would perform during the Pepsi Super Bowl Halftime Show.
