Forget about Taylor Swift's squad, Madonna's Rebel Heart tour is quickly racking up an impressive list of celebrity cameos. The latest star to make an appearance? Oscar-nominated actress Jessica Chastain, who joined the Queen of Pop on the stage to give her a spanking.
Chastain, 38, joined Madonna, 57, during a performance of "Unapologetic Bitch" in Prague on Saturday night. The pair strutted down the stage hand-in-hand before Madge led Chastain to the main stage and the actress unleashed her impressive dance moves. Then Chastain delivered a few taps on Madonna's bottom while she crawled on the floor underneath her.
"You were a very good bitch," Madonna told Chastain onstage after the song was over.
"I gave Madonna a spanking & Ive a video to prove it," the actress wrote on her Facebook page. She also shared an onstage shot from the night, writing, "The moment right before @madonna handed me a banana. The fkn QUEEN."
