DAVID Lee seems pleased to be a Knick for one more season. The talented power forward, who just signed a one-year, $7 million extension, was toasted by Jay-Z, Russell Simmons, Tyson Beckford, model Jes sica Gomez, Swizz Beatz and singer Ryan Leslie over the weekend at new Meatpacking District hot spot SL. “Beatz and Leslie even got on the mic to give Lee a shout-out,” says an onlooker. “He was pretty excited.”
