Madonna reportedly had a furious row with a female crew member on the set of husband Guy Ritchie's new film after she called the singer's adopted son a "lucky bd".

The pop superstar, who had taken two-year-old Malawian boy David Banda to watch Guy's movie RocknRolla being shot in east London, was infuriated when she overheard two crew members discussing David.

One of them asked the other what the little boy's name was, to which the girl reportedly replied: "Lucky bd".

A source told Britain's Daily Mirror newspaper: "Madonna looked astonished by what was said and words were exchanged between them.

"She seemed very protective of her son and didn't want anyone talking of him in such a manner.

"She looked really hurt and shocked by the comment and told the girl exactly what she thought of her."

The woman has now reportedly been sacked from her position as Guy wanted to show his support for his wife and son.

The source added: "It's Guy's film and Madonna is his wife, so they're very much the top dogs.

"It was a bit foolish, to say the least, so it's no surprise it sparked fireworks."

David has been living with Madonna and Guy since he left a Malawi orphanage last October.

The adoption sparked huge controversy with 50 civil rights groups claiming Madonna's application had been fast-tracked because of her star status.

Not an orphan

It later emerged that David was not an orphan. His father Yohane was forced to send him to an orphanage after his wife died when David was just a week old.

The couple - who have a six-year-old son, Rocco, together, while Madonna has a 10-year-old daughter, Lourdes, from a previous relationship - is currently awaiting a visit from African welfare inspectors who will decide if they can formally adopt David.

Penston Kilembe, director of Malawi's Ministry of Child Welfare, will observe the family at their London mansion and will grill Madonnaand Guy with a series of "sensitive questions" on subjects including, divorce, infidelity, infertility and alcohol for up to five hours each day.
