Madonna, 65, puts on a VERY saucy display as she flashes her underwear on stage before cosying up to a hunky dancer as she rehearses ahead of final concert of Celebration Tour in Brazil

Madonna brought her Celebration Tour to a close in style with her final concert as she rehearsed ahead of performing to a whopping 1.5M fans on Copacabana Beach in Brazil on Saturday - making it the biggest concert of her career.

The Queen of Pop, 65, looked incredible as she took to the stage in lace lingerie and a tiny plaid mini skirt, flashing a glimpse of underwear beneath during one raunchy routine. 

The saucy show then saw her cosying up to a hunky backup dancer as she belted out some of her most iconic hits. 

Despite just hours before the record breaking audience's arrival Madonna was as confident as ever on stage and she strutted her stuff alongside a string of colourfully dressed dancers. 

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. 

Madonna kicked-off her first-ever retrospective tour at The O2 Arena on London, England back on October 14, and proceeded to travel across Europe into the beginning of December.

She would eventually open the U.S. leg of the tour in New York City on December 13 and then take the show into the the rest of the States and Canada until an April 15 concert in Austin, Texas.

From there, the pop superstar brought the tour to Mexico City for a five night run at Palacio de los Deportes that ended on April 26.

After having thee last week off to prepare for the Celebration Tour finale in Rio de Janeiro, Madonna is now preparing for what is expected to be the largest audience she has ever play for during her illustrious career. 

The Celebration Tour not only pays homage to her long history of hit songs, Madonna also uses the platform to tell the story of how she become a global pop icon after arriving in New York City in 1978 with just $35 in her pocket. 

It would take five years until she released her self-titled debut record in 1983 that shot her to the top of the pop world with hits like Everybody, Holiday, Borderline, Luck Star and Burning Up.

Over the course of her illustrious career, the Bay City, Michigan native has released 14 studio album, with the most recent being Madam X in 2019.

Her retrospective tour came on the heels of her remix album - Finally Enough Love: 50 Number Ones, which marks Madonna scoring 50 number one hit songs on the US Billboard Dance Club Songs chart, the most number ones of any artist on any single Billboard chart. 

With sales of over 300 million records worldwide, Madonna is the best-selling female recording artist of all time.

She is also a mother of six that includes her four adopted kids David, 18, Mercy, 18, and twins Stella and Estere, 11, as well as two biological children: Rocco, 23, from her marriage to ex-husband and filmmaker Guy Ritchie, 55, and Lourdes, 27, whom she shares with ex-partner and actor Carlos Leon, 57.
