All eyes were on Paz de la Huerta at UrbanDaddy’s Chivas Day of Brotherhood gala at the Bowery Hotel on Thursday night. The leggy and physically gifted “Boardwalk Empire” star sauntered around the room in a barely-there black dress — which she insisted was not underwear. “It looks like a slip, but it’s really a dress,” she purred to us, pulling down the hemline to lengthen what there was of the garment. Meanwhile, Chris Noth was a busy man, talking up his new line of tea called Sweet Florida Dream, which benefits the Rainforest Network.
