Mariska Hargitay and Baby Amaya"Law & Order: Special Victims Unit" star Mariska Hargitay has a new addition to the family -- an adopted baby girl!

The 47-year-old "SVU" star and her actor husband Peter Hermann's little girl, Amaya Josephine, was born about a week ago and is from the U.S., according to PEOPLE. This is the couple's second child -- they also have 4-year-old son August, who is not adopted.

"I'm deliriously happy," Hargitay tells the magazine. "From the minute she was born, she was just surprisingly alert and so full of love."

She continues, "We talked a lot about mixed-race adoptions, and we are very excited that we are now a multi-racial family. We're just so happy she's here."

Congratulations to the happy family!
