Thomas Rhett's now officially a father of four, after his newest daughter arrived on Monday.
"Lillie Carolina Akins, born November 15th. 7.5 pounds of pure joy," he announced late Wednesday night on his socials.
"[Lauren Akins] you are my hero," he added, along with a photo of mom and dad with the little one.
"Watching a child being born is legit a miracle," he continued. "4 under 6 here we go!"
TR and Lauren started their family by adopting now 6-year-old Willa Gray from a Ugandan orphanage in 2017. Ada James was born in August of that same year, followed by the arrival of Lennon Love in February of 2020.
