After nearly 80 weeks on the chart, Katy Perry's 'Teenage Dream' is still going strong, with an expanded edition (dubbed 'The Complete Confection') arriving in stores March 27 -- complete with its own hit single, 'Part of Me.' But as she revealed during a recent interview with MTV, Katy's already looking ahead to her next album.

Explaining her eagerness to get down to the business of writing material for her next release, Katy said, "It's a very therapeutic thing for me, songwriting. I'm kind of one of those people who is a bit emotionless on the outside, especially in public, but what I do is I store it, and I file it, so when I need to write I can just push that button."

Musing on where her inspiration might take her, she added, "I'm going to stick my finger out there and test the waters of what the world wants, or what I need to say ... but, I'm all ears. If people want me to do another pop record, I can do another pop record ... I definitely have a lot to say right now, and in general always have. If you want an opinion, I've got one, unfortunately."

Katy went on to share one of those opinions: Namely, that she needs to return to where she started as an artist. "I just think that it's time for me in some ways to show where I came from," she said. "I've always just been me and my guitar; and I'm not saying I'm going to make that record, but I do want to get back to my roots. I've been changing my hair color too much!"
