FROM now on, Sharon Stone says, her private life is off limits. 'My new policy is this: I have a life of my own. Just a little, tiny one, but it's mine,' Stone told Entertainment Tonight. The actress, whose latest film The Quick and the Dead opens shortly, said her new policy is the result of being 'incredibly stupid in public' in matters of personal relationships. 'You realise that, 'Oh, I might not be very good in this area. I just better work that out at home',' she said. Stone's love life became the subject of gossip columns when Bill MacDonald, the producer of Sliver, left his wife, Naomi Baka, for Stone, the film's leading lady.
