Sharon Stone and Michael Douglas reunite for gala

Looking at Sharon Stone it's hard to believe that Basic Instinct came out almost 20 years ago.The actress was 34 years old when the erotic thriller hit the big screens in 1992, 14 years younger than her co-star Michael Douglas.Stone, who has just celebrated her 52nd birthday, has been lucky enough to retain her youthful looks, Douglas has definitely aged, albeit gracefully.
