Lionel Richie agrees.



"To see her leave is going to be frightening and sad, but at the same time ... hang on to your seat! She has a roar, about herself, no pun intended."

"I think I will be crying at anything," said Perry. 'It's been a beautiful journey and I love watching these kids grow and becoming this big beautiful patchwork quilt."

"American Idol" airs Sunday nights on ABC.
