Mariska Hargitay and her husband, Peter Hermann, left their NYC apartment building with their son, August, yesterday. They were also joined by the newest member of the family, 1-week-old Amaya Josephine! Mariska and Peter just shared the exciting news about adopting their daughter and the fun they had naming her. Mariska said, "I'm deliriously happy. From the minute she was born, she was just surprisingly alert and so full of love. We all talked about names because everything is a family decision in our house." The Law & Order: SVU actress recently stepped out with Peter at the Mildred Pierce premiere before welcoming their baby girl.
