What happens when Mariah Carey and Britney Spears have dinner?

No, that’s not the beginning of a joke at a West Hollywood happy hour — this really happened, as evidenced by Spears’ viral tweet on Wednesday.

“You never know who you’re going to meet at dinner parties!! Great night!” Spears wrote of an image of the two hitmakers posing for a smiley snap at dinner. “Great night! So much fun, thank you Cade!”

The dinner party took place at the luxury residence Ten Thousand in Century City, California, a rep told PEOPLE. Kate Bosworth, Tobey Maguire, and Lee Daniels were also in attendance.

Though Spears’ tweet might suggest this is the first time the singers have come face to face, they actually met in the beginning of Spears’ career, and both stars have been vocal about their adoration for each other.

Spears once admitted she paints in the nude to Carey’s jams, a confession that got Carey’s seal of approval. “hahaha! @britneyspears‘s the best!” Carey tweeted in June 2015.

And Carey famously talked about Spears in an instantly iconic appearance on Watch What Happens Live with Andy Cohen last December, during which she shoveled shade on other pop stars — including Ariana Grande and Demi Lovato — but praised Spears. “I love Britney Spears,” she told the host.

Within minutes of the latest Carey-Spears development on Wednesday, fans began freaking out on Twitter. Given the passion of their followers, the reactions below — some of which include profanities — are sure to entertain.
