Sharon Stone and boyfriend Martin Mica attend at Milan's Fashion Week.

Sharon Stone is back in the swing of things after being hospitalized during Milan Fashion Week. The 54-year-old "Basic Instinct" star took a brief trip to the hospital Saturday after experiencing migraine-related symptoms at a Fendi Fashion show in the Italian city.

"Sharon experienced migraine related symptoms, and we all felt it best that she got checked out before the amfAR event," an amfAR rep told E! News. "She was examined and given a clean bill of health. And as she said, wild horses couldn't keep her away."
