She may be a 54-year-old mother-of-four, but Madonna certainly doesn’t seem ready to leave her raunchy side behind just yet.

Continuing her tradition of shocking and causing controversy with her live shows, the queen of pop proved she’s still got it as she puckered up to her toyboy lover on stage in Porto Alegre, Brazil.

The Like A Virgin hitmaker seemed to surprise Brahim Zaibat – who at 25, is almost 30 years her junior – with a saucy smooch while her gig was in full motion.

Locking lips for all to see, Madonna certainly didn’t hold back with her very public display of passion, with the star ramming her tongue straight down the throat of her man.

Clearly happy to share their intimate moment in front of thousands of people, Brahim seemed enamoured by his cougar lady as he tenderly wrapped his arm around the singer’s waist.

While the French dancer showed off his incredible physique by going topless on stage, Madonna opted for an androgynous look for her show, teaming a black corset, with a white shirt, tie and black pinstripe trousers.

But given the Justify Your Love hitmaker’s recent antics, her amorous on-stage performance was pretty tame.

Over the past few months, Madonna has put on more than her fair share of controversial performances with her lewd and risque antics.

Last month, the star took her raunchy behaviour to a whole new level when she climbed up onto a piano and straddled the musician playing it, shoving her intimate area straight into his face.

Scantily clad in a miniscule black bustier, which barely protected her modesty, and a pair of fishnet tights, the 54-year-old singer set to work writhing around as if her life depended on it.

And if that wasn’t enough, the mother-of-four then decided to head straight to the front of the stage, where she appeared to grope herself for all to see.

But the controversy certainly wasn’t over there, with the star then throwing money all over herself as she writhed and wriggled around in her skimpy ensemble and bared her bottom to the audience.

The singer’s MDNA tour has also seen her provocatively lick a gun and be branded ’embarrassing, cringe-worthy and desperate’ by journalist Piers Morgan after she purposefully exposed her right breast while performing in Istanbul, Turkey.

One fan wrote on Twitter at the time: ‘Why is Madonna still showing off her t**s? No, it’s not sexy to see a woman who could be my grandma whipping her nipple around.’

Another added: ‘Isn’t Madonna a little too old to be flashing nip on stage? With her kids in the background (as they’re performing with her on tour?)’

On Tuesday, Madonna was spotted out and about in Buenos Aires, Argentina, ahead of her performances in the city on Thursday and Saturday.
