Mr. Big is now a big daddy!

Sex and the City stud Chris Noth and his girlfriend, Tara Wilson, are the proud parents of a baby boy. Orion Christopher Noth arrived on Friday, Jan. 18.

Together for five years, the couple, who co-own the Canadian tea house Once Upon a Tea Cup, confirmed the happy news in November.

The 53-year-old part-time Law & Order: Criminal Intent star will next be seen in the eagerly anticipated big-screen adaptation of Sex and the City, slated to hit theaters May 30.
