Madonna has joked about wanting to have sex with Game of Thrones star Gwendoline Christie.

The 57-year-old superstar invited the actress - who portrays warrior Brienne of Tarth in the HBO series - on stage at her Rebel Heart show in Sydney, Australia and she appeared to poke fun at claims she turns up drunk on stage by offering Gwendoline a drink before telling her she wants to "f***k" her.

As she offered her alcohol, Madonna told Gwendoline: "I love alcohol. Ok, here we go. Down the hatch. I have another song to do. I can't drink."

The Like A Virgin hitmaker was drinking from peculiar bananas and passed them to the blonde beauty and told her to pleasure herself with them.

She said: "Gwendoline, honey, can I give you both of my bananas? I want you to take them both and when you're lonely at night I want you to fight with them. I want you to do whatever you want with them, you've got so many orifices. You won't run out of things to do."

And the 37-year-old star replied: "Madonna, I love you."

Then she added: "I wanna f**k you."

To which Gwendoline replied: "Right back at you."

The Queen of Pop then laughed off her recent incident where she exposed a 17-year-old fan's breast.

As she told someone to escort Gwendoline off stage, she said to make sure she doesn't "hurt" anyone with the bananas and that she won't "press charges".

She told the crowd: "Make sure she doesn't get hurt with her two bananas. I really did hurt my finger. But I'm not going to press charges or anything. But thank you Gwendoline, it really is an honour to meet you."

However, Madonna insisted she doesn't drink.

Making light of recent speculation she's been drinking on stage, Madonna sipped from a glass before exclaiming: "Oh my god this water is insane!"

The singer, who played her first Sydney gig at Allphones Arena on Saturday, continued to delve into reports of unusual behaviour.

"I don't drink. So f*** you," she said. "You're not going to shut my s*** down. You're just jealous because I'm not an alcoholic".

While in Brisbane the 57-year-old had pulled down a teenage girls strapless top on stage, and joked that it was, "sexual harassment".

She was slammed by fans for being more than two hours late to take the stage down under.

Her three hour Sydney performance, which featured newer songs from the album Rebel Heart, as well as many tunes from her back catalogue was spliced with crowd interaction.

Madonna also addressed a painful custody battle with ex-husband Guy Ritchie over her son Rocco.

She dismissed any rumours about having a "meltdown" claiming it wasn't a crime for a mother to miss her child.

A Bang! Showbiz report revealed she will be flying to London following the Aussie leg of her tour to visit Rocco, because he has refused to return to her custody.

"Madonna is going to do whatever it takes to see Rocco. She wants to meet with Guy as well to sort out the situation once and for all," a source told Bang! Showbiz.

"She is in a very desperate situation. She knows she can't order Rocco to come and see her so she is making plans to go to wherever he is."
