Apparently it takes a lot of hard work to look that effortless and glamorous! Sarah Jessica Parker and the rest of the Sex and the City gang pulled a 19-hour day while filming scenes for their reunion movie inside Christie's auction house in New York City earlier this week, reports the New York Post. Close quarters or not, stars SJP and Kim Cattrall have apparently not kissed and made up. Their long-simmering feud, which reportedly erupted over pay differences for the HBO show's final season, has still not blown over. According to the New York Daily News, Kim stormed out of a recent SATC reunion party at New York hotspot Butter as soon as Sarah Jessica Parker showed up. Good thing they're both such stellar talents - fans will probably never even be able to tell anything was amiss when the movie hits the big screen.
