The "Marry Me" artist posted a photo to Instagram of his daughter and fellow country star Luke Bryan after the singer helped the little girl catch the fish.

Bryan held the red snapper up to the camera while Willa Gray proudly smiled next to the fish.

Last month, Thomas Rhett announced the exciting pregnancy news that he and Akins are expecting their fourth child, another daughter.

"Well... we are pregnant again!" he wrote alongside a photo of the couple smiling together at his concert in Texas, as his wife showed off her baby bump.

"Tonight when I was on stage in Fort Worth about to play 'to the guys that date my girls' my wife talked to me in my (ear monitors) and said 'you can tell them if you want' so anyways, now you know," he continued. "We are pumped to be having our 4th girl🙌🙌🙌."

As the post came to a close, the country star went on to joke about his future as a father of four. "Feel free to buy all the merch you want, knowing that all the proceeds are going straight to all these weddings I'll be paying for one day! Love you so much @laur_akins we always wanted a big thanksgiving table😭."
