Madonna's list of Rebel Heart tour guests reads like a rogue gallery of glam A-listers. Remember when Katy Perry screamed, "I love you, mom!" into Madge's mic last fall? And when Idris Elba legitimately opened for her in Germany under his DJ alias "Driis"?

All truly #blessed things. Still, nothing can compare to the level of affection Queen M showed to her latest guest, Ariana Grande, on Sunday night (Jan. 24) in Miami. After inviting her up onstage to lip sync and shimmy to "Unapologetic Bitch," Madonna capped the unforgettable experience by lightly spanking Ari -- a clip Ari shared on Instagram.

"I am dead. @madonna thank you for the spanking & the banana. #rebelheart #forever #unapologeticbitches ?," she wrote in the caption. Aw. Madonna called Ari the "Kewtest Unapologetic Bitch EVER!!" in a post of her own, so it looks like the feels continued long after both left the stage.

But if a mere snippet isn't enough, a fan captured the full video, which includes some post-song banter where Madonna frets over pronouncing Ari's last name correctly and makes a coffee joke. Watch the full performance -- and revel in Ari's sheer giddiness -- below.
