Salma Hayek channels Frida Kahlo onstage with Madonna during her Celebration tour

The Oscar-nominee was the latest star to join the Material Legend to serve up some 10s.

Madonna's marathon Celebration Tour wound its way into Mexico City where the pop icon brought up yet another celebrity friend, as has been custom, to help her judge her dancers in a "Vogue"-related competition.

This time, Oscar-nominee and perennial bombshell Salma Hayek made her way to the stage, with an outfit reminiscent of her 2002 film about the life of Mexican artist Frida Kahlo.

Wearing Kahlo's signature crown of flowers and a floral skirt with a Madonna-inspired bustier under a leather bolero, Hayek dutifully held up her "10" flash cards and even got lightly spanked — as one should prepare to be when attending a Madonna show.

"Thank you so much @madonna for letting be a part of your iconic Celebration Tour," Hayek wrote on Instagram, along with some pics and vids from the concert. "This unforgettable night goes in my bag of precious treasures. #VivaMexico #VivaMadonna"

Past famous guests to join the "Like a Prayer" hitmaker onstage include fellow pop queens Kylie Minogue and Ricky Martin, Stranger Things star David Harbour who appeared in Madge's 2011 film W.E., and superfan Kelly Ripa.

Madonna's Celebration Tour has been going strong since October and finally wraps up on May 4 in Rio de Janeiro.
