Katy Perry is ready to cast a spell when she takes the stage at the Grammy Awards on Sunday (January 26). And she's bringing along a rapper to help her bewitch the crowd. Katy will be joined by Juicy J to perform "Dark Horse," off her 2013 album Prism.

And if you're looking for any sort of hints as to what's to come, Juicy isn't revealing anything about the performance. Like, nothing. At all. "You just got to see it, man," he shared with MTV News, telling us it'll be different from anything he's done as a rapper. "You just got to see it. It's gonna be a great, crazy performance... Yes, most definitely."

Looking for more insight? Well, in the hours prior to the broadcast, Katy had one final pre-performance tease for her KatyCats. However, she, too, kept it vague. "Tonight... a spell will be cast... Are you ready for it?! 🔮✨🌙 @TheGRAMMYs," she tweeted.
