An unreleased song by Katy Perry allegedly produced by Dr. Luke and Max Martin, the on fire pair behind both "California Gurls" and "Teenage Dream," and originally intended for her Teenage Dream album has arrived on the web.

Reportedly, the track will be tacked onto the re-release of her top-selling sophomore album alongside a still unheard duet with Rihanna.

A breakup jam though it may be, Perry's lyrics are triumphant: "You took my life. You drained me down. That was then, and this is now. Now look at me. This is the part of me that you're never gonna ever take away from me."
