Madonna has told Guy Ritchie she wants a divorce after 7 years of marriage.
The couple are said to have held crisis talks this week, where they agreed they have drifted apart.
'They were both very calm,' says a source. 'Madonna told Guy: "I'm sorry, I want a divorce." It was quite painless but very sad.'
Guy, 39, is said to have reluctantly agreed and is rumoured to have sought legal advice from law firm Forsters.
The Material Girl is believed to have made her decision after the director told her he's quitting Kabbalah.
'A few weeks ago he told her he doesn't want anything else to do with it,' a source tells The Sun. 'It didn't go down well. The cracks are widening and Guy's latest revelation about Kabbalah has just taken a sledgehammer to them.'
Madonna, 49, has daughter Lourdes, 11, from a previous relationship, and son Rocco, 7, and adopted David Banda, 2, with Guy.
