Jennifer Lopez is J. Loaded! The singer-actress-designer has purchased a walled property in Miami’s tony Biscayne Bay. Built in 1929, the 10,852-square-foot Mediterranean abode sits on more than one acre with a gym, a sauna, and a formal eat-in kitchen. Outside there’s a bayside dock that can accommodate a large yacht. There’s also a pool, a Jacuzzi, and a party-ready gazebo that seats up to 50. The neighborhood has long attracted celebrities — Madonna and Sylvester Stallone both owned homes there for several years and J. Lo’s new digs are sandwiched between Bee Gees Barry and Robin Gibb. And if that’s not enough, pop prince Ricky Martin is reportedly just down the street.
