While on the show, Carey participated in a game of Plead the Fifth, in which she artfully dodged questions about ex-fiance James Packer and her new romance with backup dancer Bryan Tanaka before being asked about Lovato.
"Demi Lovato, I didn't know this, she kind of shaded you on social media," host Andy Cohen said. "She made assumptions about Ariana Grande, and she said, 'Mariah's a legend and she's so talented but she disses people. It's nasty the way she treats Jennifer [Lopez].' What would you say to Demi?"
"I don't know her either and so I wouldn't say anything to her," Carey responded. "She should come up, introduce herself to me, say, 'Here's my opinion, what do you think about it?' That's how you handle shit, OK?"
