Welcome to the world, Olivia Rose!

We've been on baby watch for a week now and she's finally arrived!

"On cloud nine with our new little bundle of joy Olivia Rose!! God couldn’t have brought us a more perfect gift this Christmas. What. a. miracle!! It hasn’t even been 24 hours and Tyler has been so fun to watch as a new Dad 😍 #SoInLove #ChristmasMiracle📸:@nathanchapmanofficial Deets in profile link👆🏻"

“We’re so overwhelmed with joy and already more in love than we could have ever imagined with this little angel that God has given us,” the proud new dad tells PEOPLE.

He adds, “Olivia is the best Christmas gift we could have ever asked for.”
