Saturday at sundown marked the end of bachelorhood for Jerry Seinfeld. The TV phenom, 45, married fashion publicist Jessica Sklar, 28, in a double-ring Jewish ceremony at a private penthouse in New York’s Greenwich Village. About 40 guests attended, not a one of them from the TV cast of “Seinfeld” (except for the groom, of course). Sklar’s parents paid for the event, which reportedly cost $75,000. Seinfeld’s best man, comic George Wallace, told New York’s Daily News that his toast to the newlyweds was “very dark and burnt.” The bride wore a white, spaghetti-strap, empire-waist gown designed by her boss, Tommy Hilfiger. (It was her second marriage.) The groom sported a black tux and bow tie. After the vows were exchanged, guests feasted on crabmeat hors d’oeuvres, lamb and chocolate cake with white frosting. The honeymoon destination of the couple, who spent their wedding night in Jerry’s $6 million Central Park West apartment, is being kept secret, though the Seinfelds are expected to be back in New York for New Year’s Eve.
