“Yeppers! And I’ve already started testing out ideas!” Perry tweeted moments after the announcement was made at halftime of an NFL game.
The NFL championship showdown will be staged February 1 in suburban Phoenix, Arizona.
Music industry publication Billboard reported last month that Perry would be the performer at one of the nation’s most watched television spectacles.
The most recent Super Bowl halftime extravaganza featured Bruno Mars and the Red Hot Chili Peppers and drew a record 111.5 million US TV viewers last February.
Perry, who turned 30 last month, is known for her flamboyant costumes and such hits as “Firework,” “California Gurls,” “Dark Horse,” and “Part of Me.”
Past Super Bowl halftime performers include Beyonce, Madonna, The Who, Bruce Springsteen, Prince, The Rolling Stones, Paul McCartney, Sting and the late Michael Jackson.
