blankStanford's having a baby! Well ... kind of. 'Sex and the City' actor Willie Garson is officially a father -- after having begun the process of adopting 8-year-old, Nathan, a year ago. The adoption was finalized in Los Angeles on Wednesday, the actor told PEOPLE. "From the first time I met him, I said, 'That's my kid,' " Garson, 45, gushed.
