A London judge granted Madonna's divorce petition on Friday, ending her eight-year marriage to film director Guy Richie. In the case of "Ciccone M.L. v Ritchie G.S.," Madonna claimed her spouse's "unreasonable behavior" was the cause of the divorce. Richie reportedly did not seek a hefty share of the singer's $450 million fortune. Madonna and Ritchie have two children, Rocco, 8, and David, 3, who was adopted from Malawi. Madonna also has daughter Lourdes, 12, from her previous relationship with trainer Carlos Leon. If neither side contests the divorce, it will become final after six weeks. (Phot: WENN)
