A jam-packed, celeb-attended bash at the Chelsea hotspot, The Darby, was obviously the only way to fête the gorge Coco Rocha February DuJour magazine cover, which was shot by fashion photog Nigel Barker. The two guests of honor were all smiles as they worked the crowd of admirers and friends—including model Hilary Rhoda, Angela Simmons and "Real Housewife of New York City" LuAnn de Lesseps—but I managed to corner them for a chat before the party got really crazy.
