Heidi Klum, Sarah Jessica Parker, Alan Cumming, Lindsay Lohan and Kenneth Cole were among the celebrities attending the American Foundation for AIDS Research (amfAR) annual gala in New York City on Thursday.

AmfAR is one of the largest non-profits devoted to ending the HIV/AIDS epidemic. It was founded in part by the late Elizabeth Taylor.

“Even though it's so many years on and we haven't got a cure, the fact that amfAR, and other organizations like them, manage to attract this kind of audience, that's a good thing,” said Cumming, who is openly gay, on the red carpet. “Because actually we need those people's support to make something happen.”

Parker credited amfAR for making it possible to discuss HIV/AIDS.

“I think we can all talk about it now. That we can talk about it openly, there's not the shame and the stigma attached to the disease. That you can be living with HIV and have [an] enormously productive, fulfilling, rich life,” Parker said. (The video is embedded on this page. Visit our video library for more videos.)
