Madonna's marriage success 'down to Kabbalah'

Madonna's successful marriage to film-maker Guy Ritchie is down to their devotion to studying the Kabbalah - according to close friend Vinnie Jones.

Jones, who starred in Ritchie's Lock, Stock and Two Smoking Barrels and Snatch, credits the couple's intense interest in the mystical branch of Judaism as being responsible for the strong four-year marriage.
