In Sex and the City 2, his beloved character, Stanford Blatch, gets hitched - and off-screen, Willie Garson has also taken a big life step. The actor finalized the adoption of his 8-year-old son, Nathen, in February. "Fatherhood is really great. He's amazing. I can't gush enough! I miss him every minute I'm not with him," the proud papa tells In Touch. In addition to having a doting dad, Nathen enjoys the perks of being a celebrity kid, like A-list play dates. "He plays with James Wilkie all the time," Willie says of his child's friendship with the 7-year-old son of SATC cast member Sarah Jessica Parker. The Sex star, whose highly anticipated film hits theaters today, had a dad's night out for On Location Tours' Sex and the City 2 Midnight Madness event in New York on May 26. Fans were able to hit the famous franchise's Big Apple hangouts and meet Willie himself at a special screening of the movie.
