Watch Madonna Spank and Hump Anderson Cooper on Stage in Brooklyn

By
Anderson Cooper had quite the night with Madonna.
The Queen of Pop invited Cooper on stage to dance with her during Saturday's Rebel Heart tour stop at Brooklyn's Barclays Center -- and then gave him a bit more than he bargained for.
See Madge spank and hump the CNN anchor as she sings "Unapologetic Bitch," and then gift him with a banana, in the video below.
Cooper certainly wasn't complaining! "I still can't believe this just happened," he wrote on Instagram, sharing several photos of his time in the spotlight.

Madonna also called Cooper out on her own Instagram account, writing "Anderson thanks for being my Bitch tonight!!! Hope you enjoyed the Banana‼‼‼" (By the looks of that video, he definitely did!)

Cooper isn't the first celeb to get a royal spanking from The Queen -- and something tells us he won't be the last. During Wednesday's show at Madison Square Garden, Amy Schumer did a little twerking with Madonna during her "Unapologetic Bitch" guest spot. See the moment in the video below -- and find out which other A-list celebs looked on from the audience.
