Florida Georgia Line singer Tyler Hubbard and his wife Hayley have welcomed their first child, a daughter.

"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," Hayley Hubbard wrote in an Instagram post Sunday.

The message accompanied a People magazine photo of her and her husband holding their newborn and smiling.

The child was born Saturday afternoon in Nashville.

"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," Tyler Hubbard told the magazine.

"Olivia is the best Christmas gift we could have ever asked for."

The couple have been married since 2015 and announced they were expecting their first baby last June.
