Hargitay, 47, and Hermann 44, brought home their son within a week of dealing with the paperwork.

"We never in a million year thought it would happen this quickly, but something inside of us knew that this was right, and we said, 'Yes, yes, yes!'" the Law and Order: SVU actress tells People. "We knew this was our guy. Everything about it felt right. It felt divinely right."
