The biggest stars in New York went crazy for Sex last night — turning out in droves for a premiere screening of Sex and the City's season opener. "I'm a New Yorker and it's always great to walk down the street and see yourself on a billboard," said sultry Sarah Jessica Parker, who stars in the HBO series that begins its new season on Sunday. "I try not to ponder on our good fortune, I just feel very lucky to have the success we're having." Parker and a flock of other stars wowed the crowd at the 7 pm screening at the United Artists theater on East 64th Street and Second Avenue. Fellow HBO star Vincent Pastore, who played mobster Big Pussy on The Sopranos, said he was wild about Sex. "The show rocks," Pastore said. —New York Post
