Madonna On Stage: 'I Accept I Have Lost My Son'

She took her time but an emotional material girl finally materialised on stage in Auckland last night after keeping her fans waiting for over an hour.

Madonna took to the Vector Arena stage about 10.30pm last night for the second Auckland show of her Rebel Heart world tour.

Fans took to social media to voice their frustrations with the delay.

Get on with the show already @Madonna we've paid to see ya. What are you waiting for. An hour intermission are you serious! #RebelHeartTour

TVNZ journalist Jessica Mutch asked "Where oh where is Madonna? More than an hour since the warm up act finished".

Earlier The Mail on Sunday had revealed that the pop star has conceded defeat to her ex-husband Guy Ritchie over the custody of their 15-year-old son, Rocco . The singer has told friends she has "lost the battle" after finally admitting her son does not want to live with her.

This comes after she broke down on stage during the New Zealand leg of her Rebel Heart tour on Saturday, emotionally professing love for her son to the crowd.

The mother-of-four burst into tears on the Auckland stage as she told fans: "There is no love stronger than a mother for her son," before dedicating her song La Vie en Rose to him.

The saga began last December, when Rocco left his mother's world tour to fly to Britain to stay with his film director father. Rocco then defied the superstar's pleas - as well as an order from a New York court - to return to Madonna's US home for Christmas, preferring instead to remain in Britain with Ritchie.

Now, having accepted that she is fighting a losing battle, Madonna has told friends that she will let her son stay in Britain. The 57-year-old is said to be "utterly bereft" and, as part of the peace deal, she is demanding a series of assurances that she will retain some parental influence over her only natural son.

During Friday's Auckland show - which happened ahead of these new claims - Madonna was openly emotional as she spoke of her teenage son.

Perching on a chair in the middle of the stage in front of her sold-out crowd of 12,000 people, the True Blue hitmaker spoke of her love for Rocco.

"That is my son who I mentioned earlier," she started off.

"He is actually 15, and its true, there is no love stronger than a mother for her son," she added before taking a long pause to compose herself.

She went on: "And if I talk about him too much... I might cry." The singer could be heard holding back tears, as she struggled to go on.

"But I would like to dedicate this song to him - It's a love song for a man but I know he will need one, one day,' she said through difficulty as she took a number of deep breaths. I hope he hears this somewhere and he knows how much I miss him."
