She is not backwards in coming forwards.

So it's perhaps unsurprising that Madonna has responded to allegations she was 'drunk' on stage during her performance in Kentucky on Saturday.

The Queen of Pop has her blasted critics as 'sexist' for fuelling the rumours - and insisted that she never drinks before a live performance.

Not impressed: Madonna has responded to allegations she was 'drunk'on stage during her performance in Kentucky on Saturday, branding the claims 'sexist'

Sharing an image of herself mid-song at the show, she captioned it with a lengthy missive which certainly makes her point.

'For those people who like to believe all they read i never drink and perform!!!

'My show is 2 hours and 15 minutes of non stop singing and dancing. In Louisville I made a joke about doing a stand comedy act dressed as a clown and being able to drink alcohol.'

She then added: 'Its so very interesting how society continues to not only treat me in a totally sexist way (if i a were a man no one would have said a thing) and also continue to take everything i say literally!

'Thats what happens when people don't read books and get all information from TMZ.'

Rebel Heart-broken: 'My show is 2 hours and 15 minutes of non stop singing and dancing. In Louisville I made a joke about doing a stand comedy act dressed as a clown and being able to drink alcohol.'

'Liked' by more than 65,000 people, the message generated a slew of supportive comments.

One fan wrote: 'this was the best damn concert I've ever been to. And there's no way she could have performed the way she did drunk. It was amazing!'.

The messages a a stark contrast to the criticisms which surfaced over the weekend, which saw one concert attendee tell TMZ: 'Madonna was very drunk'.

Another fan added: 'Madonna was an awesome performer but man she was a b**ch!... trashed talked Kentuckians and spoke in a fake hillbilly accent.'

The comments came after she arrived three hours late for her Louisville gig - before mocking the locals.

Apparently a lot of fans screamed obscenities at her during the show in anger but one admitted she was, 'a lil drunk but funny.'

'Working on my stand up laying down good practice!!! Thanks Louisville! the tears of a clown soon to follow the #rebelheartour,' the Material Girl tweeted with a pic of her lying on the floor at her show.

While some may have been amused by the Grammy winner's public intoxication, sadly she recently admitted she's dealing with one of the most challenging times in her life.

The 57-year-old is currently engaged in a bitter custody battle with her ex Guy Ritchie, 47, over their son, Rocco.

He had been travelling with his mum on her international Rebel Heart Tour for three months but left this past December to live with his father, Ritchie, in London.

The singer - who split from her ex after a nasty divorce in 2008 - appeared in a New York court on December 23 after Rocco refused to return home for the holidays, as reported by People.

The judge reportedly ordered her son to return home so Madonna and Guy could sort out his living situation but the teen has yet to return to the U.S.

'We all go through challenging times in our life, and that includes me. I, too, go through challenging times in my life, and right now is one of them,' she confessed at her Mexico concert last week.

'Sometimes I think I can't do a show. I don't have the energy, I don't have the strength. I come out here tonight and I can see your faces, and I look into your eyes and I see so much love and it gives me strength.'

This comes on the heels of her being seen with ex-husband Sean Penn last weekend.
