Carla Bruni, the model/singer and former first lady of France, took the stage for a performance at the Royalton on Wednesday. “I’m slightly emotional because I never played in New York,” she said before singing from her new album, “Little French Songs.” Also at the bash were Christiane Amanpour, Andre Balazs, Johan Lindeberg, singer Angela McCluskey, Jared Kushner and his pregnant wife, Ivanka Trump. Earlier, Bruni was spotted dining with Universal Music execs at a Midtown Italian spot.
