Mariah Carey rubs salt on Jennifer Lopez's wounds with latest dig

Mariah Carey reignited her longstanding, rumoured feud with Jennifer Lopez over a space conversation.

In a recent interview, the Queen of Pop left fans wondering if she lives in her own bubble when BBC Radio host Scott Mills candidly brought up Katy Perry's Blue Origin rocket ride.

The All I Want for Christmas is You hitmaker's reaction was pure gold, "Where’d she go?" she asked, sounding genuinely confused of pop star's out-of-this-world achievement.

It didn’t take long for the internet to draw comparisons to that legendary moment from the early 2000s, when Carey infamously responded to a question about J.Lo with the now-memeified phrase, "I don’t know her."

Back then, the We Belong Together singer head shake and sly smile became a meme that still lives on in pop culture lore and now fans are calling her latest reaction on Perry’s space trip the sequel.

Her oblivious attitude became an instant hit online, with fans dubbing her new vibe as "I'm just living my fantasy" era, dripping in classic Carey energy.

"I love that Mariah just lives in her own bubble! What a queen [red heart emoji]," one supporter gushed.

Another wrote, "I would love to be as unbothered as Mariah, she never knows ANYTHING nor ANYBODY [laughing emoji]."

A third chimed in saying, "She lives on Planet Mariah. Lucky girl."

"Mariah deserves an accolade. 'Where did she go?' The new… 'I don’t know her?'" a fourth added.

And while the Roar singer hasn’t stopped talking about her trip to space, fans seem... over it, with one saying, "I honestly wish I was as oblivious to that whole thing as our Mariah clearly is," throwing subtle shade at Perry’s post-space bragging spree.
