Mariska Hargitay and husband Peter Hermann have adopted a baby boy, Andrew Nicolas Hargitay Hermann.

The couple just adopted a baby girl, Amaya Josephine 6 months before Andrew, so the two kids are only a few months apart.

“Their hearts were so opened by the adoption,” a source tells US Weekly. “So they couldn’t imagine not taking the opportunity to bring another baby into the family. They are very tired and overwhelmed with the change, but overjoyed.”

So how does the new mom feel about the two new additions to the family? “Mariska is thrilled and amazed with all the new blessings and great fortune. She has more love than she imagined!”

This will be the third baby for the couple as they are biological parents to 5-year-old August.

Congratulations to the growing family!
