Ed Norton isn't one to kiss and tell. On the subject of former girlfriend Courtney Love, with whom he starred in "The People vs. Larry Flynt," Norton remains protective. He tells the December issue of Cosmopolitan that Love is still "one of my best friends in the whole world." But that's as far as he'll go. "And there's no way I'm just going to sell that out, nor will she do that to me." As for talking about his personal life at all, Norton gets really strident. "It diminishes the value of my life when everything that's mine becomes fodder for people's doctor's office reading enjoyment."
