CAP D?ANTIBES, France, (Reuters) - Stars, models and the super-rich gathered near Cannes on Thursday for a charity dinner considered the most glamorous night of the film festival, but there was one notable absence: Harvey Weinstein. Until this year, the movie mogul rarely missed the amfAR dinner, put on by the U.S.-based Foundation For AIDS Research. However, he was not there at the opening of the event on Thursday and amfAR this month appointed 25 women, including actresses Sienna Miller and Kate Hudson, to be ?honorary chairs? of the event.
