Katy Perry 'Prism' Tracklist LEAK? Photo from Los Angeles Listening Session Reveals 16 Song Titles on New Album from 'Roar' Singer

Katy Perry's third studio album "Prism" is well on its way. With only six weeks to go, Perry has been playing cuts from the album for groups of journalists in small listening sessions in New York and Los Angeles, previewing what's in store.

At a recent listening session in Los Angeles, a photograph was taken of three fans holding what appears to be the official tracklisiting for "Prism," according to Idolator.

Though unconfirmed, the tracklisting does contain known Perry cuts. "Roar," of course, is the first track on the album. Other confirmed song titles, such as "Birthday," "Walking On Air," "Dark Horse" and "Double Rainbow" also pop up on the 13-song long tracklist. It's likely that even if this isn't the exact order of songs on "Prism," these are the song titles that will appear on the album.

Three bonus tracks will also be included on "Prism," according to the picture.
