Tyler Hubbard and his wife Hayley are expecting their first child, and she celebrated the joyful occasion at a baby shower that included Jason Aldean's wife, Brittany.

The Florida Georgia Line singer and his wife are expecting a baby girl in December, and Hayley is not having to go through her pregnancy alone. She's part of a population explosion in country music this year, which has already seen Thomas Rhett, Justin Moore, Lee Brice and more stars welcome babies.

The Aldeans are expecting their son around the holidays, so Brittany and Hayley are going through many of the same things at the same time. Brittany shared an adorable Instagram photo of her celebrating with her friend on Friday (Oct. 27), in which they touch their baby bumps together.

"Celebrating BABY GIRL @hayley_hubbard & @thubbmusic," she writes. "I have a feeling our little man is going to have a lifelong crush."

Hubbard and his wife announced they were expecting a boy after a gender reveal party in June, just days after they announced the pregnancy. But that turned out to be wrong.

"God's got jokes...... After thinking we are having a boy for the last few months, turns out the blood test was wrong and we're actually having a little girl," Hubbard shared via Instagram on Aug. 4.

The Aldeans announced they were expecting their first child together in early May, and revealed they were having a baby boy via Instagram a few weeks later. They've already named their son Memphis, and they've got his nursery all set up in advance.

Wow! There Have Been a TON of Babies in 2017!
