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 on Saturday night (19.03.16) 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."
