According to her lawyers, Sharon Stone has not lost custody of her son Roan. Sharon had gone to court to try and move her son down to Los Angeles with her, where he would attend school. But the court ruled in favor of Stone's ex-husband, who lives in northern California.
According to the court minute order dated September 12th, the reason is that the child's dad Phil Bronstein, "can provide a more structured continuity, stable, secure and consistent home for the child."
The two will continue to share joint custody of Roan, but he will remain living primarily with his father up north. It seems like the court even the knows that Sharon has a few screws loose up there.
