The 47-year-old singer was a judge on season 12 of the hit music competition, and memorably clashed with fellow judge Nicki Minaj. ET spoke with Carey after her latest stop on her "All The Hits" tour with Lionel Richie at the Hollywood Bowl on Monday night, where she commented on reports that 68-year-old Richie was being tapped to be a judge.
"I would say, don't do it," Carey told ET's Carly Steel. "No, I'm only kidding. If he wants to do it, that'll be great. I think he would be really good at it."
"I don't know if you've ever been in a 15-year relationship, and then -- for a reason you don't really know -- you break up!" Seacrest said of his return on Live With Kelly and Ryan. "And I thought, 'Gosh, it would be great to get back together at some point.'"
