Mariah's response was towards Demi’s shady comment (defending J.Lo) a while back. MC went hard during a game of 'Plead the Fifth' on Andy Cohen's 'Watch What Happens Live.'
"I don't know her either" says Mariah giving some serious bitch face and rolling her eyes, before reading Demi for filth. On the other hand, Jennifer Lopez and Ariana Grande also received blunt dismissal. However, she had nice things to say about Beyoncé, Katy Perry, Taylor Swift and Britney Spears. I don't really follow Demi like that so I'm not sure if she's still on hibernation from social media, but she might want to stay there just a little bit longer.
