Ashley Olsen (pictured here Margherita Missoni) and other stars like Christy Turlington and Lisa Rinna were on hand last night for the 10th Annual amfAR New York Gala held at Cipriani.  Ashley's other half, Mary-Kate was noticeably absent from the event, apparently in hiding now since some spotlight has been shed on her since the death of her friend Heath Ledger.  The event is held in order to raise money and awareness for HIV/AIDS research
