10 Things You Didn't Know About Katy Perry

Fans discovering Katy Perry for the first time are surprised to discover that her first album was not 2008's 'One Of The Boys', but a self titled work released under her real name, Katy Hudson, back in 2001. They're even more surprised to learn that it's a Christian pop album.

As Perry herself put it "The album reached maybe 100 people." She was right, with sales struggling to reach 200. However, due to Perry's increased popularity, the album was put up on iTunes in 2012. For someone who would go on to sing about kissing girls and releasing a song called 'Ur So Gay', this is a very different side of her.
