The Basic Instinct star was at a runway show for fashion house Fendi on Friday (21Sep12) when she fell ill and was taken to hospital to undergo tests.
However, she bounced back to full health in time for a special AIDS research gala in the city on Saturday (22Sep12), which she attended as a guest of honour.
Addressing the health scare to reporters on the red carpet, she said, “I feel fine and I’m good and I’ve got a clean bill of health and I’m happy to be here.”
A representative for The American Foundation for AIDS Research added, “She was examined and given a clean bill of health. And as she said, wild horses couldn’t keep her away.”
The hospitalisation comes more than a decade after Stone suffered a brain aneurysm in 2001.
