Finley Rae Martineau Baldwin was born at 9:35 a.m. at Cedars-Sinai Medical Center in Los Angeles. She weighed 7 lbs., 10 oz. and measured 20½".
The new arrival joins older sister Avis Ann, who was born to the couple in January 2008 and who "is excited to meet her new little sister," says Baldwin's rep.
Joanne, a British former fashion model, met the Homicide: Life on the Street star, 48, during his stint in a Malibu rehab facility where she worked as a chef. They have been married for two years.
Baldwin, who recently appeared on I'm a Celebrity ... Get Me Out of Here!, also has three children from three previous relationships: Atticus, 13, Alexandra, 18, and Kahlea, 25.
