Madonna's Do's & Don't's

The Mail has learned that Madge has issued a list of demands that ex Guy Ritchie must meet while the children are with him in London.

A custody arrangement for the children remains a sticking point for the estranged couple, who were married for almost eight years.

Last week Guy, 40, hired a top lawyer in his battle with the 50-year-old over where their children should live.

The singer cannot take the children to live with her permanently in the US unless she either gets permission from Ritchie or an English court grants her leave.
