EXCLUSIVE: This is the $18 million Water Mill, NY home that singer/actress and ‘American Idol’ judge Jennifer Lopez has reportedly gone into contract over in Long Island’s tony Hamptons. After looking at several properties on the East End, the pop star zeroed in on the three-story, 14,000 square-foot home on Bay Lane. Designed by architect John Laffey, the mansion includes seven bedrooms, great views of Mecox Bay and shares a dock with the home where late actor Cliff Robertson lived.
