Congratulations are in order for Thomas Rhett. The singer and his wife Lauren welcomed their fourth daughter, Lillie Carolina yesterday.

“Lillie Carolina Akins ???? born November 15th. 7.5 pounds of pure joy????,” he shared on Insta next to a pic with Lauren and the baby. “Lauren, you are my hero. Watching a child being born is legit a miracle. 4 under 6 here we go!”

Lillie joins big sisters Willa Gray, 6, Ada James, 4, and Lennon Love, 21 months.
