Before the lovers, the films and the fame, one of Shirley's treasured roles was that of big sister to her younger brother, actor Warren Beatty. "When we were kids, I really did protect him," she says. "[And] he always wanted to tag along with me and my girlfriends, but I always said, 'No, no, go home.'"
Today, Shirley says her relationship with Warren is still going strong. "It's terrific," she says. "I see him whenever I'm in California."
