Madonna 'utterly bereft' post custody loss of son

Madonna seems to be shattered after her estranged son Rocco denied to live with her.

The 'Material Girl' singer broke down in tears at an event in New Zealand recently, while dedicating a song 'La Vie en Rose ' to her estranged son.

At the concert, she told fans, "there's no love stronger than a mother for her son."

The 57-year-old singer and her ex-husband Guy Ritchie are close to a deal in the custody dispute over whether their 15-year-old son will remain in London or will have to return to the United States, reports News.com.au.

Reportedly, Madonna has accepted that she is not getting back Rocco, but is holding out to get him for one weekend per month.

The custody case was heard in Manhattan Supreme Court on March 2, with Madonna and Ritchie listening in by phone.

According to reports, Madonna's lawyer asked for Ritchie to be held in contempt for not bringing Rocco back to Manhattan to settle the dispute as laid out in their divorce.

Rocco has been living in London with his father since December.
