Madonna dons green balaclava mask and classic Material Girl garb for soundcheck ... trends now

Madonna is bringing her Celebration Tour to a close in grand fashion with a free concert at Copacabana Beach in Rio de Janeiro, Brazil.

With the massive show set for Saturday, which could tally up to 1.5 million fans on the beach, the Material Girl herself was on the stage conducting a sound check to make sure everything goes smoothly come show time.

Despite this being a session to work out any potential issues that may arise, the pop superstar appeared to be taking this more like an actual show decked out in a stylish all-black outfit and a green balaclava mask.

Madonna (born Madonna Louise Ciccone) sang snippets of her songs to backing music while dressed in shorts with a bustier over a matching sheer top and a glittering silver ensemble around her neck.

The Queen Of Pop also added some of the extra fashion touches her fans would expect that includes fishnet stockings, a black lace gloves that covered most of her arms and bulky leather boots.

The pop icon rehearsed intensely, like she typically does, surrounded by an assortment of international dancers and musicians. 

While the megastar singer, 65, wore a balaclava mask on stage as she put on a very raunchy display while practicing her jaw-dropping performance, she also wore a knee brace for rehearsals to help avoid any injuries. 

The Like A Virgin star previously revealed she had to undergo regenerative treatment after suffering extreme pain due to knee surgery.

Eventually, she decided to finally undergo knee surgery in April 2020 followed by hip surgery in November 2020 as well as 'regenerative treatment for my missing cartilage.' 

Billed as 'the biggest dance floor in the world,' the show out front of the Belmond Copacabana Palace Hotel doesn't require fans to get tickets, while Brazil's TV Globo broadcasts the concert live, according to Rolling Stone.

The local mayor's office has prepared an operation equivalent to the one used for New Year's Eve celebrations in Copacabana, which is one of the most famous in the world that typically brings in some one million people. 

The concert will only be broadcast locally in Brazil. Fans outside Brazil can livestream the big event online on a cable streaming service that carries TV Globo or through a Virtual Private Network (VPN).

Copacabana Beach has been the site of a number of huge concert gatherings over the years, including Rod Stewart, who had 4 million concertgoers for is show in 1994, while the Rolling Stones reportedly had a crowd of 1.5 million in 2006.
