The Crimson Peak star joined the singer for the surprise appearance Saturday while she was in the Czech Republic shooting a new film entitled, “The Zookeeper’s Wife.”
Madonna welcomed Chastain onto the O2 arena stage during her performance of “Unapologetic B**ch” to walk with the star on the runway leading up to the main stage. There, Chastain showed off her impressive dance moves before the pop star crawled down to the floor, inviting the 38-year-old to spank her.
“I gave Madonna a spanking [and I’ve got] a video to prove it,” Chastain wrote on Facebook alongside a video that captured the moment.
Madonna thanked Chastain for coming up onstage on Instagram writing “Tonights Sexy and Beautiful “Unapologetic B**ch.” Thank you Jessica Chastain. Thank you Prague!,” next to a close-up photo of the smiling actress dancing amongst the concert’s performers.
On Friday, Madonna’s Rebel Heart tour made headlines when it grossed $46 million in its first two months.
