Hayden Panettiere is officially a mom! The 'Nashville' star and her fiance, Wladimir Klitschko, welcomed their baby girl on Dec. 9.

Baby Kaya Klitschko was born weighing 7 pounds, 14 ounces, and measuring 20 inches long.

“We are over the moon and madly in love!” the new parents tell People.

Panettiere, 25, and Klitschko, 38, got engaged in 2013, but they have not yet set a wedding date. The actress kept many details about her pregnancy private, though she did reveal the baby's gender at the Primetime Emmy Awards.

“I’ve lived a very big life, and I don’t feel my age, and I feel like I was born to be a mother,” Panettiere says. “Sometimes people speak about [having kids] like, ‘Your life ends -- you’re never going to be able to do anything again!’ And I’m like, ‘What are you talking about?’ Motherhood is the most beautiful, exciting thing, and there’s nothing that I feel like I can’t accomplish while having children in my life.”

Congratulations to the couple!
