Katy Perry’s “Firework” has been exploding across the sky this week—from the EMAs in Madrid, to NYC’s Roseland Ballroom and now at the Victoria’s Secret “Heavenly Bodies” 2010 runway show. Last night, the Cosmo UK cover gal performed her explosive hit while wearing a flashy purple ensemble, before changing into a yellow and black bustier for a medley of “Hot N Cold”, “California Gurls” and “Teenage Dream”.
