During Sunday night’s Watch What Happens Live!, host Andy Cohen had a hard time getting a straight answer from Mariah Carey about her love life, but the singer was ready to open up about who she does and does not know. Harking back to one of Carey’s most delicious shady moments when she answered a question about fellow very-successful diva Jennifer Lopez by saying, “I don’t know her,” Cohen decided to play a game with Carey called “Does! She! Know! Her!” In the segment, Ariana Grande and Jennifer Lopez are entirely unknown entities to Carey, who could barely deign to respond to Cohen’s insistence that Grande was channeling a young Mimi. Carey admitted to meeting Lady Gaga when Gaga was in the audience of her Christmas show, and same with Taylor Swift. The only other diva Carey was willing to admit she knew was Britney Spears, which makes the fact that Britney likes to paint topless while listening to her more sweet. Maybe? Watch the clip above with the game and the clip below where Carey notes someone else she doesn’t know, Demi Lovato.
