Fortunately, the pop star just dropped a pretty big hint. Not about WHAT she will be wearing, but about WHO she will be wearing, which at least lets us know we can expect some serious awesomeness in the wardrobe department.
In a new interview with E! News, Katy revealed that she will be wearing designs by her good friend, Jeremy Scott, who is also a favorite of fellow pop star Miley Cyrus.
"I called one of my best friends and I thought this would be an incredible moment to share with one of my favorite designers, Jeremy Scott. So he'll be designing all of my costumes," she told the site.
She also says that we can expect to see more than one look during the 12.5-minute performance because well...one outfit simply wouldn't suffice. "On my real tour, the Prismatic World Tour, I have nine, ten different costumes. So I would feel very bored if I didn't change my look at least once on the show," Katy explained.
We also know a couple of other things about the show, like that Lenny Kravitz will be making an appearance and that her entrance and exit will be "superb."
We can't wait to see what else Katy has planned!
