Los Angeles, California - Katy Perry just paid Ariana Grande a serious compliment before taking her last bow as an American Idol judge after seven seasons.

While speaking to EXTRA about American Idol's season 22 winner Abi Carter, the Teenage Dream singer said that Abi's "voice is unlike anything I've heard in pop music."

She continued, "The last time I said that I said that about Ariana Grande when she went on The Ellen [DeGeneres] Show."

"I was like, 'Oh, this girl is the best singer of our generation.' So, I don't say that lightly," Katy recalled saying of the eternal sunshine artist.

The Wide Awake songstress was honored with a medley of her greatest hits, including Teenage Dream, Dark Horse, and California Girls, on Sunday's three-hour American Idol season finale.

Katy announced her departure from the show in February and plans on heading over to Brazil for the Rock in Rio music festival in the fall.
