Sex and the City’s Mr. Big just welcomed his own Mr. Little. Actor Chris Noth and longtime girlfriend Tara Wilson, who named their 7-pound, 10-counce son Orion Christopher, have already received well-wishes from S.A.T.C. co-star Sarah Jessica Parker.

“I'm thrilled for him because I think first of all he's going to make a wonderful, wonderful father,” the 42-year-old actress told an ET reporter at the Sundance Film Festival, where Ms. Parker is promoting her new film Smart People—a romantic comedy co-staring Dennis Quaid and Thomas Haden Church. “He found a lovely lady to have a child with. It's the perfect time for him and I think he's very ready,” she added.
