Actress Melanie Griffith Wednesday gave birth to a baby girl, Dakota, the daughter of actor Don Johnson. The baby, the couple's first, was born at 2:49 p.m. A nursing supervisor would release no information about the delivery, but the couple's publicist, Elliot Mintz, said mother and baby were doing fine. Johnson, 39, who is in Texas filming the movie "Hot Spot," was present at the time of delivery, Mintz said. Griffith and Johnson were married in 1976, then divorced and remarried this year.
