It's difficult to stay cool when pregnant, no matter what month of the year. Fortunately for three country singers' pregnant wives, it's bikini season!

Thomas Rhett's very pregnant wife Lauren, Jason Aldean's not-as-ready-to-pop wife Brittany and Tyler Hubbard's just-pregnant wife Hayley are three proudly showing off their baby bods on Instagram. Rhett recently snapped this pic of his first-time-pregnant wife of nearly five years. She's due in August:

Mrs. Jason Aldean is due a little later this fall — the couple shared they were pregnant after the 2017 ACM Awards, although it's not clear if she knew at the time. Recent photos show her belly is swelling, and she's enjoying any opportunity to show it off:

Hey if you've got it, flaunt it! That's been a rule of thumb for pregnant women at awards shows in recent years. Other country ladies expecting soon include Ashley Monroe, Brantley Gilbert's wife Amber and Chris Lucas' (LoCash) wife. Lucas broke the news they were expecting in September during an interview Taste of Country last winter.

Hayley Hubbard, Tyler from Florida Georgia Line's wife, is growing a baby boy. They've taken some artistic photos of the still-developing baby bump. Who would even know she's pregnant?
