Tyler HubbardFlorida Georgia Line’s Tyler Hubbard and his wife Hayley are adding to their family, announcing they are expecting their first child in December of this year.

“There’s a lot of excitement — it’s something we’ve looked forward to for a while,” Tyler told People in this week’s issue.

“We haven’t put a whole lot of pressure on ourselves to just try to have a baby or not try to have a baby,” Tyler explained. “We’ve just been going with it and seeing what happens, and it’s been fun to live in that moment for a little while of, ‘If it happens, great. If it doesn’t, great as well.’ That’s where we’ve been, and it’s been fun to trust God and know that his timing is perfect. It really is so perfect.”

Just after getting the exciting news, Hayley took off to Africa to “advocate for maternal child health initiatives”(People). “I’m not going to lie, it was pretty rough,” Hayley said about traveling while dealing with the sickness that comes with being pregnant. “I was definitely exhausted.”

“But it put things into perspective for me because we were working in Malawi with the UCSF School of Nursing and so we were in a lot of hospitals with women that just had babies. They were with their newborns in these dirty congested hospitals and no sheets on the bed — conditions you would never want to have your baby in — so suddenly I didn’t feel as sick or feel as bad.”

Finally able to share the news of Hayley’s pregnancy, her and Tyler are even more excited about taking on this challenge.

“To be honest, our world, at this point in our life, it revolves around what we want it to revolve around — our wants and our needs and our desires, what we have going on in our schedule … and all that’s about to change,” said Tyler.

“Trying to have the balance of raising a kid and raising a family with the lifestyle that we have, and the pace of life that we live — it’s going to be fun, it’s going to be challenging and something that we’re really, really excited about,” Tyler continues. “There’s all kinds of emotions on both ends of the spectrum from excitement to nervousness. But the excitement definitely outweighs the nerves.”
