Mariah Carey has already explained "I don't know her," the diva's famous line about Jennifer Lopez, to Andy Cohen. She took it a step further on Sunday's Watch What Happens Live, updating Cohen on the status of her relationships with a handful of divas.

"People love the debate over whether or not Mariah Carey ‘knows' Jennifer Lopez so much that there's even an ‘I don't know her' t-shirt," said Cohen.

"They make their own merchandise," Carey said of her fans, a.k.a. lambs.

"I know, they bring their own merch," said Cohen, laughing before taking the focus back to Lopez. "Do you know J.Lo at this point?"

"The audience member said it," explained a faux-exasperated Carey. "I mean, let me just tell you, I've spoken to you at least three times, right? I mean, we've had many conversations together. Do you think I know your every waking thought?"

Attempting to get on Carey's level even more, Cohen asked, "Do you know me?"

"Yes," replied Carey. "If somebody asked me, we've met, we've spoken, we've had conversations, we've talked. I know you."

With the definition of "I don't know her" now even clearer, Cohen kicked off his Carey-inspired game, "Does! She! Know! Her!?" Read on for Carey's responses.

Lady Gaga
"Well, she came to my show," explained Carey. "She was very sweet. She came to my Christmas show at the Beacon Theatre. She came there and we had a nice conversation."

Cohen pushed for more info, prompting Carey to reply, "Well, we've met. And we've had a good conversation in my dressing room. It was very sweet and I enjoyed the moment."

Ariana Grande
"What about Ariana Grande? Do you know her?" asked Cohen.

"No," dead-panned Carey.

"When I looked at her early in the career, I kinda thought, ‘Wow, this is an homage to Mariah a little bit,'" said Cohen. "Did you feel that?"

"Child, I don't know when early in the career was," said Carey with a straight face.

Taylor Swift
"Very nice girl. Met her once. She was really sweet. She came up to me."

"Never had a conversation with her."

Katy Perry
"Nice girl. She came to my show as well."

Britney Spears
"I love Britney Spears," said Carey, smiling and showing more enthusiasm for Spears than anyone else.

"She said recently that she likes to paint in the nude listening to Mariah," shared Cohen, making Carey laugh.

Miley Cyrus
"Uh, I think we met in a bathroom with, I don't know. I don't know," said Carey.

Demi Lovato
Later in the show, Cohen addressed Demi Lovato, who earlier this year said Carey "disses people" and that the way she treats Lopez is "nasty." "What would you say to Demi?" asked Cohen.

"I don't know her either, and so I wouldn't say anything to her," explained Carey. "She should come up, introduce herself to me, say, ‘Here's my opinion. What do you think about it?' That's how you handle s—, okay?"
