(digitalspy.co.uk) - Madonna and Guy Ritchie will end their seven-year marriage in November, say reports.According to The Mirror, the pair have decided to delay the announcement until Madonna's Sticky And Sweet world tour finishes.A source said: "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 are better off as friends. It's sad, but they're determined to keep it amicable."The pair recently denied rumours they were splitting, despite reports that Madonna has hired divorce lawyer Nicholas Mostyn QC.
