Katy Perry had a Vegas moment of fan-girl whatever last night as she attended the one and only Mariah Carey‘s Las Vegas residency show, #1 to Infinity, at Caesar’s Palace! She took to Instagram (as any sane person would) to exclaim that she’s part of Mariah’s “Lambily 4life.”

But it didn’t stop there. Katy got the opportunity of a lifetime to meet Mariah after the show. And thus, that moment gave birth to this glorious photo.

And the Goddess herself took to Twitter to give Katy a shoutout:

Thank you to @katyperry​ and her friends for coming to the show. You looked beautiful! 😽 ❤️ pic.twitter.com/MtrQsQyTGT
