Former Hasidic rapper Matisyahu last year shaved his beard and pais, staples of ultraOrthodox Jewish men. But his cleanshaven look has left him unrecognizable. At Sundance this weekend, he stood outside TAO nightclub for 10 minutes because the door managers didn’t know who he was. He wasn’t allowed in until another friend recognized him. Matisyahu wasn’t the only VIP seen waiting to get into parties — spies told us Nicole Kidman’s agent got held up outside CAA’s bash Sunday night.
