Set your DVRs: Katy Perry will be stopping by ABC's Good Morning America on Friday and she's got something you're going to want to hear.
First, the singer will discuss her brand-new video for "Roar," which premieres Thursday, as well as her new album Prism . Then, around 8:30 a.m. ET, she'll be making some kind of "special announcement." It's not clear what this announcement is: it could be a tour, a contest or any number of other things, so be sure to tune in on Friday and check it out.
