Chris O'Donnell, 30, and wife Caroline Fentress are celebrating the arrival of their second child, a baby boy named Christopher Eugene O'Donnell, Jr. According to O'Donnell's publicist, Jennifer Allen, Fentress gave birth to the 7 lb. 8 oz. boy last Tuesday. "They are all home and doing wonderfully," Allen says. The couple also has a one-year-old daughter named Lily. But O'Donnell's role as proud father won't keep him out of the public eye for long. His new movie, "Vertical Limit" -- the story of a mountain climber's quest to save his sister atop the world's second highest peak --- hits theaters December 8.
