SHARON Stone gathers no moss when it comes to expanding her family – she’s just adopted her third child. Sources say the “Basic Instinct” bombshell became the proud mom of newborn Quinn Stone this month. “He’s absolutely adorable and the apple of his mommy’s eye. Sharon is tickled blue,” said one pal. Quinn joins two brothers, Roan, 6, and Laird. Stone’s publicist, Cindi Berger, would neither confirm nor deny our scoop.
