Natasha was very involved in AIDS research through amFar, prior to her death in March. Stone was close friends with the actress, and wanted to show respect to her during the annual Cinema Against AIDS fundraiser.
An emotional Stone told the audience, "This year we lost an angel from our amfAR family. It was one of those random events that leaves you in a state of shock and profound grief. In March, the funny, graceful Natasha Richardson was taken from us.
"People say, 'Oh, she can't really have been that great or graceful.' She was. 'That funny, charming, sweet and elegant.' She was. She left behind her husband and two stunningly beautiful children and an unfinished mission to help us find a cure for AIDS."
A short film was screened, highlighting the work Richardson did for the charity. Stone pledged $50,000 in honor of Natasha, and then Annie Lennox took to the stage to perform Talking To An Angel, which she dedicated to the late star's memory, saying: "That was for Natasha."
It’s still so hard to believe Natasha Richardson is gone. She touched so many lives, and hopefully with organizations like amFar, her legacy will live on.
