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 divorce from Russell Brand. Luckily, however, she's also got the music to justify the hype.
Her second album Teenage Dream cemented Katy's status as a pop heavyweight. She equalled Michael Jackson's record of six consecutive No 1 singles from one album, with massive hits like Firework and California Gurls. The album's re-release saw the single Part of Me top the charts in both the UK and the US.
Though Katy's split from husband Russell Brand had the tabloids salivating, she let the music do the talking. Katy came back with a Roar on her third album, Prism, which was chalk-full of heartfelt tracks exploring the breakdown of her marriage. It wasn't all sadness and gloom, however, with the hit record exploring themes of growth, progress, forgiveness and the freedom to love again.
