Alicia Keys said she's sad to hear of Randy Jackson's departure as a judge from "American Idol," but she doesn't know if she would want to replace him.
"I don't know if I'd want to be a judge," she said after her performance, quoted by People magazine.
"That's so sad," Keys said of Jackson's move. "I think he's amazing. I've really loved him for lots of years."
Current and former "American Idol" contestants echoed Keys' sentiment.
"He's been there since the beginning, and now none of the judges are going to be the same," she said.
Season 12 finalists Kree Harrison and Candice Glover will go head-to-head in next week's two-part finale for Jackson's last episodes.
Glover said he should reconsider his decision.
"I definitely don't think any season after this is ever going to be the same without 'Yo Dawg,' " she said.
