Thomas Rhett

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

Tell us you're a dad without telling us you're a dad.

Everyone got in on the fun, even Rhett's newborn baby girl, Lillie.

Congrats to the proud parents and their growing girl gang!

Lyrically, Rhett co-wrote a nostalgic summer love song that stings just like it should.

A few candidates seem likely while one singer feels like an exciting long shot.

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

The lyrics are bound to make you smile.

Thomas Rhett's surprise new song gets the party started, just in time for the singer's return to live music.

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.
