Watch Jessica Chastain Give Madonna a Spanking

— -- Jessica Chastain got down and dirty with Madonna at the pop star's latest Rebel Heart tour stop in Prague.

The 57-year-old singer plucked the Oscar-nominated actress, 38, from the Czech Republic audience to dance with her on stage during a performance of "Unapologetic Bitch."

Chastain, who shimmied her hips in front of Her Madgesty, made no apologies after Madonna dropped down on all fours in front of her for a spanking.

"I gave Madonna a spanking & Ive a video to prove it. #rebelheart #unapologeticbitch," the "Martian" star bragged on Facebook later, alongside the video.

The actress also posted a photo from the concert on Instagram, writing, "The moment right before @madonna handed me a banana. The fkn QUEEN."

Chastain is not the first star to dance with Madonna or receive a banana from her. The singer has been previously joined on stage by Katy Perry, Anderson Cooper, Amy Schumer and Diplo.
