It's a diva duel for the ages. Entering the ring donning sequins and sass is Mariah Carey. She's been throwing shade at Jennifer Lopez for years — claiming she doesn't know who J. Lo is.
It all started here. This GIF's origin dates back to an early 2000s interview when Carey was asked what she thinks about Lopez. She responded with, "I don't know her."
And not knowing J. Lo in the early 2000s meant not knowing the woman who made us all want to wear pepto-colored velour tracksuits or that she was totally snubbed for an Oscar for her work in "The Wedding Planner."
But apparently Mariah Carey wasn't a part of the entire generation that smelled like Glow by J. Lo. Carey claimed to remain ignorant of Lopez through the years despite their similar careers — including being "American Idol" judges and now having a Las Vegas residency.
"What do you think of people referencing, 'I don't know her,' all these years later?" TMZ asked.
"I still don't know her," Carey replied.
Lopez shared a different side of the sing-off with Wendy Williams when she explained who she scoped out in Vegas before she started her own show.
"I didn't see Mariah because at the time, she wasn't playing," Lopez shared.
"Who? No, I'm playing. That's what Mariah said about Jennifer one time," Williams joked.
"She does say that. She's forgetful, I guess," Lopez said.
And it seems Carey agrees. She subtly shaded J. Lo again Tuesday night on 'Watch What Happens Live!'
"Do you know each other?" Andy Cohen asked.
"No!" Carey exclaimed.
"She says you know her."
"I'm very forgetful."
So, the shade saga continues. Honestly, it just sounds like these two aren't friends. But as my show choir teacher once said, a duet is the first step in friendship.
