From the previous post we know that Justin and Selena are spending the 4th of July long weekend in the Hamptons, a neighborhood for the rich (yes I watch the "Real House Wives of New York"). Not sure exactly where they're staying but yesterday they spent the day on Russell Simmon's yacht. Russell is the head of Island Def Jam, Justin's record company.
