Who could forget their infamous reality TV show The Simple Life? Just seven years ago, the world was introduced to relatively unknown Hollywood socialites Nicole Richie and Paris Hilton. Back then, the inseparable duo were rich best buds who took on a variety of low-paying jobs all in the name of guilty reality TV. Five seasons later, their friendship ended amid rumors that Richie hosted a viewing party of Hilton’s sex tape at a party. A long feud ensued, and the former best pals were suddenly enemies. “Nicole cannot stand being around me because I get all the attention,” Hilton once said. The pair later worked things out and are now friendly again, but not nearly as close as they once were.
