Carey revives her classic line during a new interview on Andy Cohen's chatshow.

Mariah Carey has directed her infamous “I don’t know her” line at Demi Lovato in a new interview.

During a German TV interview well over a decade ago, Carey was asked about fellow pop singer Jennifer Lopez, with whom she is rumoured to have a long-running feud. “I don’t know her,” Carey replied matter-of-factly.

The line has since been embraced by fans as a classic example of “throwing shade”. It’s appeared on T-shirts, been turned into a long-running internet meme, and even had club nights named after it.

These days, Carey is clearly aware of the line’s popularity. Asked on camera about Lopez last year, she replied knowingly: “I still don’t know her.”

During an appearance on Andy Cohen’s chatshow Watch What Happens Live on Sunday night (December 18), Carey revived the line again when she was asked about Demi Lovato, who has called her treatment of Lopez “nasty”.

“I don’t know her either,” Carey replied. “And so I wouldn’t say anything to her. 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?”

Later in the interview, Carey also claimed not to be aware of Ariana Grande, whose debut album was frequently compared to Carey’s classic ’90s hits. “Honestly, I’m not familiar – I listen to hip-hop more than I listen to pop music,” Carey said. Watch below.
