Mariska Hargitay has adopted another baby, six months after the adoption of a baby girl.

Andrew Nicolas Hargitay Hermann, who was born over the summer, joins sister Amaya Josephine and big brother August, 5.

We never in a million years thought it would happen this quickly, but something inside of us knew that this was right, and we said 'Yes, yes, yes!' Hargitay told People.

We knew this was our guy. Everything about it felt right. It felt divinely right, she added.

The Emmy Award and Golden Globe Award winning actress and her husband first announced the adoption of Amaya Josephine, who is from the U.S., in April.

The new additions to the family are already getting along, according to Hargitay.

They'll lie in the crib together, and she'll hold his hand and put her arm around him . . . she's already so protective of him, she told People.

Hargitay, 47, and her husband, Peter Hermann, have been married since 2004, after meeting on the set of Law & Order: SVU.
