Marchesa designer Georgina Chapman was one of the few notable folks without a 13-year-old tagging along at last night’s Cinema Society screening of Twlight: Eclipse. At that age, the Marchesa designer confessed, she was obsessed with Guns N’ Roses. Due in August, the 34-year-old says her pregnancy has gone smoothly and she feels very good. Any cravings? “Nothing,” Chapman said. “And I’m nearing the end and nothing exciting has happened.” She and husband Harvey Weinstein have not chosen names for the baby girl. “I want to meet her first,” she said, laughing.
