Madonna's highly anticipated free concert on Rio de Janeiro's Copacabana Beach has caused a stir in the neighborhood, with over a million fans expected to attend. For retired resident Mario Renato Borges, it's a fitting tribute to the iconic singer.

"Welcome, Queen," read posters near the massive stage set up on the Brazilian beach, where Madonna will perform the biggest show of her 40-year career on Saturday, marking the culmination of her "Celebration Tour."

The 65-year-old American singer arrived in the coastal city on Monday after completing over 80 shows in Europe, the United States, and Mexico. This concert will be her sole stop in South America.

Madonna traveled to Brazil with three planes and 270 tons of equipment, according to her production company. She is staying at the luxurious Copacabana Palace hotel, connected to the stage by a suspended catwalk where dozens of fans have gathered, hoping to catch a glimpse of the pop icon.

With free admission, organizers anticipate the creation of the "world's biggest dance floor," with up to 1.5 million people expected to attend — a figure previously achieved only by the Rolling Stones on the same beach in 2006.

Despite chaotic traffic, residents like Borges are excited for the concert, recognizing Madonna as the queen of pop.

Madonna's fourth performance in Rio is expected to inject around 293 million reais (US$57 million) into the local economy, a revenue 30 times higher than the city authorities' investment, according to the mayor's office. Approximately 150,000 foreign visitors are expected to flood the city, with most hotels already fully booked.

"This will undoubtedly be one of Rio's biggest international events, boosting our economy and attracting tourists from Brazil, Latin America, and around the world," said the city's Tourism Secretary Daniela Maia.

Madonna fever is palpable in Rio, with businesses capitalizing on the excitement by offering Madonna-themed merchandise. The Lix printing shop in the Saara shopping district has seen a surge in demand for personalized fans, hats, and mugs inspired by the "Material Girl."

Security measures are also in place, with an operation comparable to New Year's Eve celebrations deployed in Copacabana. Some 4,500 agents will be deployed, along with drones and facial recognition cameras, ensuring safety during the event.

Despite the anticipation, locals like Nagila Alves express their enduring admiration for Madonna and her timeless appeal. As excitement builds, residents and visitors alike are preparing for a memorable evening celebrating the music and legacy of one of pop's most enduring icons.
