Lauren Akins and Haley Hubbard did their best to get their daughters to synchronize smiles for the camera, but it just wasn't happening.

It was a girls' day out for the families of country singer Thomas Rhett and Tyler Hubbard, and it looked like fun ... except Willa Gray really wanted in that swimming pool! With Akins, Hubbard and good friend Kailey Dickerson (singer Russell Dickerson's wife) behind them, the tiny trio did what kids do when asked to smile for the camera. Every parent knows it's as easy as trying to get three puppies to hold still and pose.

"Besties by the pool," Akins writes, tagging Dickerson and Hubbard in the first of three photos. Flip through to see the others. The women hold their smiles while their daughters turn and offer a mix of expressions. Ada James looks concerned, or maybe hungry. We're not sure what Olivia Rose is thinking, because we can't get past those chubby little cheeks!

The Rhetts and Hubbards are good friends. In fact, they were on a safari together when Akins and Rhett found out they were expecting baby Ada not long after they started working to adopt Willa Gray. Both kids arrived in 2017. The Hubbards welcomed baby Olivia in December.

It's not clear whose infinity pool they enjoyed. Rhett is currently on tour with Kenny Chesney while Florida Georgia Line are playing fairs and festivals, including WE Fest in Detroit Lakes, Minn. on Aug. 3.
