Katy Perry has revealed the tracklist for her new album Prism, which revealed the star co-wrote every song on the new, 16-song release.

Prism is Perry's third major label release and follows the huge success of current single 'Roar', the opening track on the album.

Track credits reveal the full list of big name writers involved on the project, including Dr.Luke, Bonnie McKee, Max Martin, Klas Ahlund, Sia Furler, Greg Kurstin, Emeli Sande and boyfriend John Mayer.

Perry's collaborator's read like a who's who of the pop music world, but her next release could see an entirely different collection of stars, as she is planning to record a folk record.

"I'll probably turn into more of a Joni Mitchell," she says in a new interview with Billboard magazine. "As I inch towards my 30s, I think my fourth record will be more of an acoustic guitar album. That's where I started when I was first discovered by Glen Ballard and got my first record deal."

She also adds she feels hesitant about ditching the mainstream sounds which has scored her international, and record-breaking, success, and claims boyfriend John Mayer has been advising her on maintaining her career.

"I can't get ahead of myself. I'm still doing the work: I'm a good balance of left and right brain, and to be an artist with a long career, you've got to have both," Perry added.
