Since bursting onto our TV screens in 2008, Katy Perry has certainly ruffled a few feathers along the way.
The girl-kissing, gospel singer-turned global pop megastar frequently sets tongues wagging with her provocative outfits, eye-popping videos and, of course, her high profile relationship with Russell Brand. Luckily, however, she's also got the music to justify the hype.
Her albums One Of The Boys and Teenage Dream have produced a string of smash hit singles including Hot 'n' Cold, California Gurls, Firework and E.T., the latter of which featured the ever-controversial Kanye West.
And, with her own fragrance, a sell-out world tour and a role in the new Smurfs movie, it looks like we're going to be seeing even more of this California Gurl in the future.
