Katy Perry’s Sixth Number One? (VIDEO)
Katy Perry's Teenage Dream album is big. Like ginormous. It's was released in August of 2010 and it's already spawned five number one hits in Teenage Dream, California Gurls, Firework, E.T. and Last Friday Night (T.G.I.F.). Having five number one songs off of one album is almost unheard of... especially from a sophomore effort. But Katy is poised to break more records.
