Guy Ritchie claims his marriage to Madonna disintegrated when she started planning their sex life in her diary around her sessions in the gym.
The 50-year-old singer's life was so regimented, he said, that even their time in the bedroom was meticulously planned for weeks in advance - something which took all of the thrill out of it for him.
The revelation came as Guy sat down with lawyers to talk over the reasons why he felt the eight-year marriage broke down this week.
The split has become increasingly acrimonious with accusations flying from both sides in recent days.
