Florida Georgia Line star Tyler Hubbard and his wife, Hayley, shared the exciting news that they're expecting their second child with fans on Feb. 10, but their families found out at Christmas.

The couple used a photo of their smiley daughter, 1-year-old Olivia, sitting in the snow next to a sign that reads: "Only child expiring August 19, 2019! I'm going to be a big sister!" to tell fans. It's the same image Tyler and Hayley used to tell those closes to them about the pregnancy.

"We were in Sun Valley when we found out, so we took that photo and we kinda printed it out and put it in our parents' stockings for Christmas — that was how we told them," Hubbard recalls during a recent interview with Taste of Country Nights, adding that everyone in the family is excited about the new baby.

Of course, big sister Olivia has to also be excited to get a baby brother, a piece of news that was revealed to even Tyler and Hayley with a surprise gender reveal on The Ellen DeGeneres Show.

Maybe the new baby boy will join Olivia in weighing in on the songs that their daddy makes with his FGL counterpart, Brian Kelley.

"Olivia's favorite song is definitely 'Simple,'" Hubbard shares. "Anytime we turn that on, she could be screaming her face off or crying and I'll turn that song on and she'll completely stop crying and start dancing and smiling. So, it's kinda our go-to when she's upset about something."
