People magazine reports that the couple brought home Andrew Nicolas Hargitay Hermann, who was born over the summer, within a week of filing their adoption 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!'" Hargitay told the magazine.

This is the third child for the couple, who also have a biological son, 5-year-old August.

A source told Us magazine that bringing home two babies in six months hasn't been easy for the couple: "They are very tired and overwhelmed with the change. But overjoyed."

Hargitay and Hermann have been married since 2004.
