When “SNL” star Jay Pharoah showed up early to a surprise birthday bash for Wyclef Jean at Gina la Fornarina on Second Avenue, he killed time by running across the street to squeeze in a set at Comic Strip Live. “Jay arrived 45 minutes early, so he ran to do impromptu stand-up across the street,” an impressed spy said. Also at chef Paola Pedrignani’s restaurant Saturday night were models Jessica White and Chanel Iman. Katie Couric was spotted feeding gelato to boyfriend John Molner.
