LIONEL DANCING ON THE CEILING AS KATY QUITS!

Idol gang happy to see diva go!

LIONEL RICHIE isn’t crying over co-star Katy Perry’s departure from American Idol, according to insiders who say the All Night Long singer is actually jumpin’ with joy!

“It takes a lot for an old pro like Lionel to dislike somebody, but Katy gets under his skin and always has,” spills an insider. “She comes across as stuck up. She’s harsh with contestants while Lionel loves being a mentor. Katy doesn’t seem to have patience with these young wannabes.

“Lionel won’t be sad seeing her go. He’s happy he won’t have to listen to her catty, cutting remarks!”
