"I could not a dreamed up a better life."

This Mother's Day, Thomas Rhett had a special message to share with his wife Lauren, who is mom to their four daughters.

Her famous husband couldn't resist a hilarious response.

Thomas Rhett and his wife Lauren adopted their oldest daughter, Willa Gray, in 2017.

"We're already kind of in the chaos phase with young kids," the singer explains.

Congrats to the proud parents and their growing girl gang!

On Instagram Story, Lauren Akins shared video of her daughter in action.

Rhett's three daughters have since come around to the idea of a baby sister -- but maybe they'll still get a baby brother one day.

Anyone with kids can relate to this.

Thomas Rhett shared the news onstage in Texas ... and he also shared the sex of the new baby.

Rhett and Lauren have decided to be forthright about their ups and downs in the hopes that others won't feel alone.

These two are going to be very busy!
