The wait is officially over — Hayden Panettiere gave birth to her first child on Tuesday, Dec. 9.

“We are over the moon and madly in love!” Hayden and fiancé Wladimir Klitschko told 'PEOPLE.'

Their baby girl, who they decided to name Kaya, weighed in at 7 lbs., 14 oz., and measured 20 inches.

The 25-year-old actress was very open about her weight gain during her pregnancy — and even rocked a bikini in her final months!

“I’m 5 feet, 2 inches, and I started out at 106 pounds and guess how much I weigh now? Around 145 pounds,” she told 'Hello' magazine. "And the worst part is that my feet are still size five and they're going, 'What's going on with all this weight?’ They're about to snap from underneath me with the strain.”

We're sure the 'Nashville' actress is happy that her pregnancy is finally over.

Congrats to the happy family!
