No stranger to the VMAs stage, Perry has won four MTV Video Music Awards, including the highly-coveted, "Video of the Year" for her #1 worldwide smash-hit, "Firework," and performed her hit "I Kissed a Girl" at the 2008 show as well as a stellar cover of Queen's rock anthem "We Will Rock You" with Aerosmith's Joe Perry in 2009.

Perry's new album PRISM is set for release on Tuesday, October 22.
