Richard Johnson Page Six - Is Zac Posen trying to invent the latest dance craze? The designer showed up to celebrity stylist Christopher Niquet's birthday party at Le Royale Tuesday and karate-danced his way through the night. "He looked like he was doing ninja moves over and over and then he started teaching everyone else what he was doing," said one partygoer. "He was in jeans and looked like he hadn't shaved in a week."
