Julia Roberts, Penélope Cruz, Kate Winslet. When it comes to spokespeople, Lancôme always seems to have a thing for film’s leading ladies–until now. Their latest face has never starred in a motion picture; rather, she’s a fixture of the French fashion scene. Daughter of Vogue Paris editor Carine Roitfeld, Julia Restoin Roitfeld will star in ads for the beauty brand’s spring 2011 makeup collection, Ultra Lavande. With Alexa Chung’s Lacoste campaign and Dree Hemmingway for Paco Rabanne, it seems that more and more companies are looking to sign it-girls for beauty deals (though this is nothing new for Restoin Roitfeld, who posed for Tom Ford’s Black Orchid fragrance ad in 2006). Lancôme’s (very purple) makeup ad was shot my famed photographer Mario Testino, who is also Restoin Roitfeld’s godfather. Talk about a royal fashion family!
