Madonna joins Salma Hayek for 'Vogue' in Mexico City as holiday tour wraps up

Salma Hayek helped Madonna wrap up her celebratory career tour in Mexico City, where the actress appeared on stage with the Queen of Pop during her performance of “Vogue” at the Palacio De Los Deportes on Friday night (April 26 ).

Hayek, dressed in a Frida Kahlo-inspired ensemble, stepped in to judge the tour's dancers' fashion. (Hayek portrayed the iconic painter in the 2002 biopic Fridafor which she received an Academy Award nomination for Best Actress.)

Hayek reacted to her experience with Madonna on Instagram in a post on Saturday, writing, “Thank you so much @madonna for letting me be a part of your iconic holiday tour. This unforgettable night goes into my bag of precious treasures.”

Madonna has just one show on her current itinerary, a May 4 free concert on Copacabana Beach in Rio de Janeiro, Brazil, which Visit Rio officials say is expected to draw two million fans. Admission to the show, sponsored by Itaú Bank, is on a first-come, first-served basis on the day of the event. Fans unable to attend will be able to watch the show live on TV Globo.

Mexico City hosted Madonna for a series of five concerts at the Palacio De Los Deportes. Last weekend, on Saturday, April 20, the singer opened up about her love of Mexican culture and Kahlo, telling the audience how she discovered the painter's art as a young girl.

“As you know, I have a long history, a long history with Mexico,” said Madonna, who reportedly met with the Kahlo family at their home in the city's El Pedregal neighborhood.

“When I was a girl,” she said, “I discovered Frida Kahlo. I went to the only museum there was in Detroit, and there were Diego Rivera murals everywhere, but to be honest, I was more interested in a small picture in a corner of a beautiful woman with braided hair and intense eyes. “

The Celebration tour began in the fall, after a delayed start due to Madonna's hospitalization for a severe bacterial infection over the summer.
