Singer Thomas Rhett and his wife, Lauren Akins, have welcomed their fourth daughter, Lillie Carolina.

The 31-year-old Rhett shared the news Wednesday on Instagram alongside a photo of himself with Akins and their baby girl at the hospital, along with the caption: “Lillie Carolina Akins born November 15th. 7.5 pounds of pure joy. @laur_akins you are my hero. Watching a child being born is legit a miracle. 4 under 6 here we go!”  Akins posted on her own account: “Our little miss Lillie Carolina Akins was born on November 15th and our family couldn’t be more over the moon about our littlest joy.”

Rhett and Akins married in October 2012 and have three other daughters together: Willa Gray, 6, Ada James, 4, and Lennon Love, 21 months.
