Madonna found herself a brand new BFF to play with on stage at the weekend, this time in the form of pint sized pop princess Ariana Grande.

Yep, Queen M invited the Bambi of music to join her during her Rebel Heart tour stop in Miami over the weekend, and also (obviously) took the opportunity to spank her.

COOL.

Anyway, having just ticked the ultimate wish off her list, Ari couldn't help but get all excited on Insta over what'd just happened.

Again.

And again.

Still, gotta be kind of awks to be spanked in front of thousands of people, no?
