While we know ex-husband Russell Brand won't shy away from talking of their relationship in his future autobiography, we can't help but wonder what Perry will be singing about.

During a session last week at the I Create Music Expo, Perry filled attendees in on what to expect from her new music. Here are five things we learned, via recaps from Billboard and The Hollywood Reporter as well as Perry's Twitter.

1. Expect a team of familiar collaborators. Perry has been in the studio with many of the writers and producers from her 2010 release Teenage Dream, including Max Martin ("Teenage Dream," "The One That Got Away"), Dr. Luke and Greg Wells ("Pearl," "Not Like he Movies") as well as Bonnie McKee ("Last Friday Night (T.G.I.F.), "California Gurls"), Sia and Greg Kurstin.
