Juicy J on Katy Perry: "She's a Genius"

Juicy J was pretty impressed by all of the famous "and rich" people on the GRAMMYs Red Carpet, but clearly no one could impress the Memphis rapper more than one Katy Perry.

In case you missed the memo, Juicy guested on Katy Kat's hit single "Dark Horse" and the two are set to wow with a performance this evening.

The Three 6 Mafia member and twerking scholarship judge says we're in for quite the surprise, but while he refused to give any deets on the performance, he did have something to say about his Ms. Perry.

"Katy is a genius, glad she called me up," he told Fuse News' Jack Osbourne.

"It's a blessing; she put me on a hit record."

Check out the rest of the interview above to find out more Juicy facts.

(Hint: he's a Rod Stewart fan!)
