Named Dixie Pearl, the couple's daughter was born at 1 a.m. June 21 and weighed 7 lbs, 11 oz. She measured in at 22 inches, a rep for Kings of Leon confirms.
"Mom, Dad and baby are happy, healthy and enjoying their new addition," the rep tells Us.
This is the first child for Aldridge and her husband, who wed at San Ysidro Ranch in Montecito, Calif. in May 2011. Aldridge wore a custom Vera Wang dress for the outdoor ceremony.
This isn't the only happy news for the Followill family: Caleb's bandmate and brother, Jared, 25, proposed to model Martha Patterson April 11 "at his home in Nashville," a rep told Us in May. "We're all excited for the newly engaged couple." Jared presented her with a 4-carat cushion-cut diamond set on a diamond-covered band.
