Madonna Works It

Working out to Madonna is like shopping to Lindsay Lohan, she just can't get enough. The singer is so fitness-obsessed that she bought the house next door to hers in London's Marylebone neighborhood for almost $12 million in order to convert it into her own personal gym. She plans to knock out some walls so that she can move back and forth between her residence and her new gym without being seen. Until she gets the proper permits, we'll get a sighting of the buff material girl every once in a while!
