Hayden Panettiere Welcomes Daughter Kaya

Hayden Panettiere just took center stage: her baby girl is here!

The Nashville star is a new mom after welcoming her first child with fiancé Wladimir Klitschko on Tuesday, Dec. 9, her rep confirms to PEOPLE exclusively.

Daughter Kaya Klitschko weighed in at 7 lbs., 14 oz., and measured 20 inches.

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

The actress, 25, stayed mum throughout much of her pregnancy, letting her growing belly speak for itself.

But while walking the red carpet at the Emmys in August, Panettiere not only showed off her bump in a glittery gown — she also confirmed the sex of her baby the way!

“I want to go shopping, I want to paint the room,” she said after letting the sex slip.

In November, the mom-to-be admitted she was ecstatic to find out she would be welcoming a daughter. “I’m thrilled that I am having a girl first because I feel like I know a lot about raising a strong woman,” she told Hello magazine.

“I feel very empowered myself and I think my daughter will, too.”

Panettiere announced her engagement to heavyweight boxing champion Klitschko in October.
