Madonna commenced her Rebel Heart tour last night in Montreal, and the pop icon brought out a special victim, er, guest...Diplo. The two are friends and collaborators, so that in itself wasn't too shocking, but what she did to him onstage was a little more so. 

During "Unapologetic Bitch," he came out and danced with the singer for a second, before she turned him around, bent him over, and smacked his ass...repeatedly...and then straight-up humped him. When he stood back up, Diplo looked a little frazzled but seemed to be a good sport. And is if that's not strange enough on its own, Madonna gifted the producer a banana before he exited the stage, exclaiming "So many things you can do with a banana! Right guys?" Awkwarddddd.

We'd like to think Diplo called Drake up later that night, sobbing. Now you're not the only one, Drizzy. 

Watch the ass-slapping and banana-giving footage below.
