The fairy-tale romance between Simple Life siren Paris Hilton and Backstreet Boy Nick Carter has come to an end. After seven months of very-public canoodling, Hilton's rep confirmed the breakup on Friday, saying her client is "busy focusing on her career." Carter, meanwhile, issued a statement saying he wanted "to be free to date other people." He added he went out partying with his pals on Thursday night, "immediately after the breakup took place. This is the prime of my life. I'm back in the studio with the guys and about to go on tour." Translation: He's beyond devastated.
