On Easter Sunday, the country artist took to Instagram to share an adorable photo of all four of his daughters together.
All wearing matching blue dresses with little white flowers, eldest daughter Willa Gray sits in the middle of the couch holding baby Lillie, who's grinning from ear to ear, while big sisters Ada and Lennon pose beside them.
