At Madonna's penultimate Australian concert this week she decided to bring out "unapologetic bitch" Game of Thrones star Gwendoline Christie to dance with her on stage.
And things got, shall we say, a little crazy.
There was play swordfighting with bananas.
A lot of excellent dance moves.
But mainly a lot of spanking.
Madonna told Gwendoline, who plays badass Brienne of Tarth in the HBO series, to bend over because she'd "been a bad girl" and then proceeded to spank her.
Then she told her she wanted to fuck her, because she's Madonna.
And they both seemed to LOVE it.
Watch the whole thing here.
