Madonna has admitted she married husband Guy Ritchie to make her "look good".The pop superstar wed the English film director in December 2000 and now confesses they tied the knot for all the wrong reasons. She revealed: "I went into the marriage saying, 'He's fantastically talented, very witty, very smart. He's going to make me laugh and look good because he's so successful and, of course, he's gorgeous, sexy and handsome'"However, the mom-of-two says she now realises what marriage is about. She added in an interview with Britain's Tatler magazine: "None of these things mean anything after you've been sharing a life together for a few years and you're dealing with raising children and scheduling and finances"You have to go back to what is the point of marriage. You go to school to learn how to learn and I think marriage is about learning to learn as well "Diane Sawyer once said to me that a good marriage is a contest of generosity - I thought that was a good thing to say"
