Hayden Panettiere has given birth to a baby girl!

The Nashville star and fiancé Wladimir Klitschko welcomed daughter Kaya Evdokia Klitschko — their first child — on Tuesday, Dec. 9, her rep confirmed to People.

The little princess weighed in at 7 lbs., 14 oz., and measured 20 inches.

“We are over the moon and madly in love!” the ecstatic new parents gushed.

The 25-year-old actress kept the pregnancy on the down-low for the majority of the past nine months, but the Heroes alum eventually revealed to E! News that she was expecting a baby girl.

“I’m so ready to hold my baby girl—I’m going to be a very hands on mom,” she told Hello! magazine. “I’m thrilled that I am having a girl first because I feel like I know a lot about raising a strong woman. I feel very empowered myself and I think my daughter will, too.”

And as to her baby girl’s name, Kaya Evdokia, Panettiere said it was very important to the couple to find a name that worked in American and Klitschko’s native Ukrainian.

“We have to make sure that it is American and Ukrainian all at the same time,” she said. “That’s a little rough…we’re still working on it.”

Panettiere announced her engagement to Klitschko in October, but says she’ll take her time before walking down the aisle.

“I’ll tell you one thing for sure: I am not walking down the aisle 40 pounds heavier than usual in a wedding dress with a huge pregnancy belly stitched in,” she told E!. “Not happening.”
