Jon Bon Jovi is truly living like a rock star in his $24-million duplex in New York. His 7,452-square-foot property is basically the penthouse of the New Museum’s 158 Mercer Street building. It has a large dressing room, marble bath, and two chef’s kitchens. Bon Jovi bought the pad in 2007 and these days, it’s said to be worth around $42 million already. He sure made an excellent investment!
