Madonna 'is spying on Guy Ritchie'

Madonna has started spying on Guy Ritchie, according to sources close to the film director.

The popstar, 50, is keeping tabs on Ritchie's legal meetings about their impending divorce, reports The Sun.

Ritchie was apparently shocked when he discovered the singer knew about a meeting he held with his father and sister at the weekend.

"They discussed the divorce and how Guy could stand his ground against Madonna and her PR machine," said a source.

"When Guy found out [Madonna knew about the meeting], he lost the plot. He said, 'How can you set fire to our whole world? Why go to such lengths to destroy me?'

"But Guy knows it would be unusual if Madonna wasn't monitoring his every move. She's a control freak and there's so much at stake."

Ritchie has also reportedly compared Madonna's actions to something "concocted by the KGB".
