The Bravo executive gushed over “how much ‘I don’t know her has become part of the lexicon” and “how much time [they] have spent in these chairs discussing whether or not” the singers know each other.

Carey, 56, noted, “The thing is, I was being honest when I said it. So I don’t know how it became so big. Honesty isn’t really something that becomes big most of the time.”

Cohen — without name-dropping Lopez — asked, “To clarify, you still do not know her right?”

Carey sighed, replying, “How could I suddenly know [her], you know?”

The audience erupted in laughter — and Instagram users couldn’t get enough of Carey’s “forever iconic” response.

One fan labeled her the “queen of shade,” while another pointed out, “Mariah is such an intelligent person for her to be so funny on the fly like this.”

Lopez’s rep did not immediately respond to Page Six’s request for comment.

The “Hustlers” star, notably, clapped back at Carey’s original diss on the “Wendy Williams Show” in 2016 by calling the Grammy winner “forgetful” and insisting they had met “many times.”

Carey, meanwhile, doubled down that same year, telling Cohen, “Apparently, I’m forgetful. Because I don’t remember the fact that it was like, ‘Hi, I’m so and so,’ and then we moved on.

“I don’t know her,” she continued at the time. “Like what am I supposed to say?”

On Wednesday, Carey also addressed her longstanding feud with Eminem when asked whether the rapper asking her to play his mom in “8 Mile” started their beef.

“There is truth to that,” she acknowledged. “I really don’t care. Whatever he said, then I’m that. Fine. Not really, but that’s a rap lyric.”

Carey also rolled her eyes over her ex-husband, Nick Cannon, insuring his balls last year for $10 million, saying, “Lord, help me.”
