Katy Perry is reteaming with pop mastermind Dr. Luke for her new album, and she's half finished with the followup to 2010's Teenage Dream. "When I put myself on a timeline, when I tell the record company when I want to release the album, that's when the race starts," Perry said yesterday at ASCAP's I Create Music Expo, as reported by Billboard. "That's when I put pressure on myself."

Dr. Luke has produced some of Perry's biggest hits, including "Teenage Dream," "Last Friday Night (T.G.I.F.)," "E.T.," "I Kissed a Girl" and "Hot n Cold." Perry is also working Max Martin, Greg Wells, Sia and others on the new record. She described what she likes best about working with her various collaborators.

"[Wells] allows me to vomit words," Perry said. She continued, "Max and Luke push me the most. As a team we have certain strengths. With Max, it's melody choices, Luke is production and I'm topline and melody." Perry also called working with "California Gurls" and "Teenage Dream" collaborator Bonnie McKee "like an emotional abuse session" and noted that she presented "Teenage Dream" three times before it was approved for recording.

Perry also said she's written a new song called "Double Rainbow" with McKee and Greg Kurstin, though she picked "Firework" as "the most important song I've written." She said singing the song last October with a fan with autism was "the most important performance of my career so far."
