Duran Duran rocked a crowd of hundreds who gathered Sunday night at the Fendi O’ extravaganza to fete Fan di Fendi, the new women’s fragrance. The Eighties super group played hits such as “Notorious,” “Girls on Film” and “Rio” to adoring fans, who included the likes of Karl Lagerfeld, who said he’d been following the band “since the beginning.” Alber Elbaz is a big admirer, too. “I love them,” he gushed. Meanwhile, Audrey Marnay said she’s the new face of the Longchamp brand. After making her way down the glitter-strewn carpet, Nora Arnezeder said her next film, “La Croisière,” is due out in April. In the comedy, she plays a kleptomaniac. Arnezeder is also working on an album, but don’t expect its release anytime soon. “I want to take my time,” she said. Other partygoers included Lou Doillon, Noémie Lenoir, Shingai Shoniwa (who changed her outfit half-way through) and Jade Jagger.
