The couple's healthy daughter arrived weighing in at 7 lbs., 14 oz., and measuring 20 inches, according to People Magazine. "We are over the moon and madly in love!" the first-time parents said.

The proud parents first met in 2009 at a book party and dated for two years before splitting up but they reconciled this April (2013). Since their engagement last October (2013), they haven't been able to set a date due to both individuals' busy schedules.

News of the 'Nashville' star's pregnancy was first reported this past May, and Panettiere confirmed she was carrying a child while taking part in the ALS Ice Bucket Challenge in August. "I accept my ALS Challenge," she said in an Instagram video. "I renominate Kacey Musgraves - you're not getting out of this, Wladimir Klitschko, and my unborn child."

The former 'Heroes' star has been very open in the past on the subject of starting her own family with Klitschko, and in an interview with the May 2013 issue of Glamour, she spoke candidly of motherhood.

"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," she said to the magazine. "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?'"
