Rocker/actress Juliette Lewis has completely lost contact with her ex-boyfriend Brad Pitt - insisting fame has changed the Hollywood hunk. The pair dated for three years in the early 1990s and starred together in the 1993 thriller KALIFORNIA. But while Pitt has since started a family with Angelina Jolie (JUN06), the JULIETTE + THE LICKS singer is single after divorcing her husband of four years, professional skateboarder STEVE BERRA, in 2003. Lewis says, "We're strangers now. He's not in my universe. We were both unknown when I went out with him. "I just have this idea that being really famous is just not the kind of thing that would happen to me. And I don't have anything else to say about my high-school relationship."
