Ageing pop-star Madonna is apparently splitting with her husband Guy Ritchie at the end of her forthcoming world tour.

The singer and the film director have reportedly decided to end their seven-year marriage but won?t announce it until her ?Sticky and Sweet? tour finishes in Mexico on November 29th.

A source close to the couple told a British newspaper: “Although the marriage is coming to an end, they don’t want to say anything until the tour is over.

“They live like brother and sister rather than husband and wife and thought it best to call it a day. There’s been speculation about them having furious rows, but they have just grown apart. They’ve decided they’re better off as friends. It’s sad, but they’re determined to keep it amicable.”

Madge is planning to divide her time between her properties in London, New York and Los Angeles when the split happens.

Her New York apartment is getting renovated to accommodate her children and staff.

Madonna is also said to be ?devastated? her brother Christopher is writing a book detailing the singer’s sex and drug-fuelled past, something which he blames the breakdown of her marriage on.

An insider said: “Madonna is very saddened by Christopher’s behaviour. As far as she’s concerned her brother going public is the ultimate betrayal. He can’t need the money that badly.”
