Olivia Rose Hubbard is a big sister! Her famous dad, Florida Georgia Line member Tyler Hubbard, and mom Hayley welcomed a new addition to the family on Monday (Aug. 19).

Luca Reed Hubbard was born early Monday morning -- his due date! -- People reports, at 3:40AM Nashville time. He weighed 8 lbs, 11 oz., and measured 20.5 inches long when he was born.

“Hayley was absolutely amazing throughout the whole labor. She was so patient, positive and strong. She honestly made it look easy,” Hubbard shares. “I feel so blessed to get to raise a family with such an incredible woman and amazing mother. She was meant for this, and it’s so special to see.”

Baby Luca's name, Hayley tells People, "means 'bringer of light' ... [and] reminds us of Italy, which is one of our favorite places." His middle name is also his father's middle name. "We wanted Luca to have a little piece of Tyler in his name," Hayley explains.

The Hubbard family announced Hayley's pregnancy in February, with a gender reveal following during a Feb. 21 appearance on Ellen. After the Hubbards both made their guesses as to Baby No. 2's sex -- he thought boy; she though boy, "but because I think it's a boy, it's probably a girl" -- Kelley and DeGeneres pressed a big red button to deploy confetti cannons ... full of blue confetti.

"I thought we were just gonna cut a cake or something on Friday!" Hubbard said with a laugh.

This time, the big reveal proved to be correct. In June of 2017, the Hubbards disclosed the sex -- or so they thought -- of their first bundle of joy at a gender reveal party that they shared on social media. However, in early August, the couple learned that their original test results were incorrect, and Olivia would be a she, not a he.

“[Luca name isn't] not the same one we had picked for our ‘first boy,'" Hayley shares. “For some reason, that name just didn’t seem to fit the way Luca did.”

The Hubbards have been married since 2015. Olivia was born in December of 2017. Hayley says Luca looks quite a bit like his older sister did when was was born.
