Panetierre's daughter, Kaya Evdokia Klitschko weighed in at 7 lbs. and 14 oz. and measured 20 inches when she was born, People exclusively reported. Though the 25-year-old actress had remained mum about her pregnancy, she gave in a little detail as she revealed the sex of her baby while walking the Emmys red carpet in August.

In November, Hayden Panettiere told Hello Magazine that she was ecstatic to discover that she would be welcoming a daughter, which she later named Kaya Evdokia Klitschko.

"I'm thrilled that I am having a girl first because I feel like I know a lot about raising a strong woman," she said. "I feel much empowered myself and I think my daughter will, too."

Since giving birth to daughter Kaya Evdokia Klitschko, Hayden Panetierre enjoyed her first night of uninterrupted sleep courtesy of her fiance's [Wladimir Klitscho] mother.

"Wlad's mom was desperate to take the baby for a night," Panettiere stated. "She looks like she didn't get much sleep, but I feel well-rested!"

Together with her 38-year-old fiancé, Panettiere also gushed about their first-time parenting experiences as they introduced their bundle of joy, Kaya Evdokia Klitschko, The Daily Mail reported. The proud parents said that they are "over the moon and madly in love."

The "Nashville" actress also admitted that adjusting to life as a parent has been "such a surreal experience and so out of body."

"You're suddenly looking at this little thing like, 'Oh, that was you in my belly this whole time,'" she said. "[We're] just getting to know her."

Panettiere also revealed that recovering from giving birth has been quite a challenge for her.

"I'm limping around. I'm still trying to figure out what [pregnancy] has done to my body, how it's changed it," Hayden shared, "What's temporary and what's permanent. I feel like an 80-year-old woman trying to go down the stairs, you know - please tell me this is temporary! But I know some things will never be the same again."

Meanwhile, first-time mom Hayden Panettiere also spoke with so much enthusiasm whenever asked about her newborn daughter, who is only two weeks old.

"She's really so sweet," Hayden gushed, as reported by E! News. "I'm sure that's the way it's meant to be, because when they are putting you through the ringer you're like, 'You are so lucky you're cute!'"
