Their marriage lasted just four years but these two are ready to go for round two – if the price is right.

Madonna got predictably weird at her charity gala at Miami’s Art Basel on Friday night.

The 58-year-old treated a crowd of the rich and famous, that included ex-husband Sean Penn and Leonardo DiCaprio, to ‘an evening of music, art and mischief’ benefiting her charity Raising Malawi.

The benefit saw the star auctioning off pieces of her jewellery and art collections, celebrity experiences – including a week at Leo’s Palm Spring house – and even a custom car inspired by her.

It also quickly became a slightly saucy trip down memory lane for the Rebel Heart singer and ex Sean.

Real Housewives of New York star Bethenny Frankel captured the singer and the 56-year-old actor’s antics on Snapchat.

In an attempt to get bids up on one of her necklaces, Madonna – who did a number of costume changes throughout the evening – zeroed in on her wealthy ex.

Madonna cheekily offered to marry Sean again if he was willing to bid $150,000.

While the Oscar-winner was quick to agree, he was outbid by other wealthy folks wanting the jewels.

But Sean was still rewarded for his attempt at generosity, with the actor called up on stage.

As the bridal waltz played, Sean crawled onto stage and under his one-time wife’s legs as she asked him if it reminded him of anything.

Turning up the heat – despite Madonna’s young son David, 11, being at the gala – Sean then handcuffed Madonna.

The singer quipped: ‘The many moments that were our marriage.’

While filled with sexual innuendo, the police were also involved a few times during their romance with Sean once arrested for assaulting a photographer.

But wait, Madonna has more, with the musical icon declaring: ‘I’m still in love with you.’

It was certainly the perfect moment for the sentiment, as the pair then joined forces to auction off intimate unseen photographs of their 1985 wedding taken by Herb Ritts.

The couple met and married in the same year but Madonna went on to file for divorce in 1987.

The star later withdraw the papers only to refile two years later.

Madonna and Sean have remained friends and recently a number of outlets have suggested that they are something more than just pals.

Aside from getting cozy with her ex, Madonna also entertained her guest with her burlesque performance Tears Of A Clown.

She also made a few jokes about the election asking the crowd what happened as she did her part by offering ‘blow jobs’ for votes for Hillary. 

The 58-year-old also performed a musical number with Arianna Grande.

Helping her auction off some of the pricey items was Chris Rock, David Chappelle and David Blaine.

James Cordon was the master of ceremonies through the evening which saw some unusual items come up for sale.

While the singer’s artwork – which included pieces from Cindy Sherman and Damien Hirst – brought in serious bidders, there was a lot of experiences up for grabs to entice bigger spenders too.

This included a private game of poker with actors Edward Norton and Jonah Hill, a private performance by magician Blaine, a customized Fiat 500 inspired by the star and a portrait session with photography duo Mert Alas and Marcus Piggott.

But Madonna made plenty of money for her charity before the bidding event began, as according to The Guardian, attendees paid $5,000 a seat and $150,000 for a the ‘philanthropist package’ which is for a table of 10, access for four people to a VIP cocktail reception and a photograph with Madonna.

Throughout the evening of Madonna’s ultra-VIP charity event at Miami’s Art Basel, guests were urged by the hostess to take advantage of the ever-flowing Perrier-Jouët Belle Epoque at their tables to help them dig deeper into their pockets.

It seems the fancy champagne worked as the auction raised over $7.5 million.

Madonna started Raising Malawi in 2006, and the charity seeks to improve children’s lives in Malawi.

The charity is currently building a pediatric surgery and intensive care unit – the country’s first.

Both Madonna’s son David Banda – who spoke to the crowd after a touching video – and her daughter Mercy, 10, are from Malawi.
