British director Guy Ritchie is making another film with his wife Madonna - in their first collaboration since 2002's cinematic disaster Swept Away.

The Snatch film-maker is planning to make a behind-the-scenes documentary of Madonna's Confessions On The Dance Floor tour, which kicks off in Los Angeles.

A source says, "Things have been rocky between them of late, and they both feel this will give them something to concentrate on outside their relationship."
