Madonna shares a cheeky snap of her pert derriere from controversial Australian tour... and praises 'beautiful' daughter Lourdes in new social media posts

She's put in a series of erratic performances on her Australian tour as her legal team continues to battle her ex-husband Guy Ritchie for custody of their son Rocco.

But Madonna, 57, defiantly posted a cheeky snap of her pert derriere on Instagram on Monday and insisted she was having a blast on the down under leg of her Rebel Heart tour.

The iconic singer looked in fantastic shape in a pair of skin tight leather pants underneath a sheer skirt which she teamed with a corset and black vest top.

The star has clearly been hitting the squat rack to maintain her peachy rear and toned thighs, with not an inch to pinch anywhere to be seen.

Her long golden locks fell in waves down her back as she made her way up some steps while performers danced around her. 

She captioned her post: 'Melbourne was fun! Brisbane here we come! ❤️#rebelheartour'

However, fans of the singer were left stunned at her Melbourne gig on Saturday night in which she reportedly swigged tequila from a fan's hip flask and appeared drunk. 

She allegedly branded her ex-husband a 'son of a b***h' and begged 'someone please f*** me'.

Madonna couldn't contain her anger during a second mumbling show and begged the crowd: 'Somebody take care of me please. 'Who is going to take care of me?'

And falling off a tricycle she appeared to ramble as she told fans she had 'messed up' her songs, before joking: 'You would think it was in my DNA,' according to The Sun

The following day, the singer posted a snap in support of her stunning daughter Lourdes' new modelling campaign for Stella McCartney.

The 19-year-old is appearing alongside a host of other young influencers, going virtually make-up-free in the ad images, allowing her to show off her natural beauty.

Sporting soft lilac-coloured hair for her modeling debut, Lourdes, who is known as Lola to her friends and family, joined Canadian musician Grimes, actress Amandla Stenberg, and animal activist Kenya Kinski-Jones for the Pop fragrance shoot.

Full of pride, Madonna wrote: 'Looking Gorg.............. lola leon'

And just days before, she posted another shot revealing she was missing her daughter, writing: 'I miss this Beautiful Girl! Looking forward to seeing her very soon!' 

The Like a Prayer singer is also mother to two adopted children David Banda, nine, and Mercy, 12.

Last week, Madonna's representatives told a High Court judge in London that she wants to 'heal the wounds' in her dispute with Guy over the future of their son.

Mr Justice MacDonald has been listening to submissions during private hearings in the Family Division of the court as the bitter custody battle continues.

Rocco was at the hearing on Friday as was Guy and his wife Jacqui, while Madonna was unable to attend due to touring commitments.
