A smiling Janet Jackson, who turned 45 earlier this week, was resplendent in a long wine-colored skirt and loosely tied green top at the 18th Annual amfAR Cinema Against AIDS Gala held during the Cannes Film Festival at Hôtel du Cap-Eden-Roc in Cap d’Antibes, France. The black-tie event, which included a cocktail reception, dinner, and live auction, attracted Gwen Stefani, Naomi Campbell, and a dapper Kanye West, who arrived on the arm of former French Vogue editor-in-chief Carine Roitfeld. Très chic!
