A king and his queen now have a little princess.
The baby girl arrived at 1 a.m., weighing in at 7 lbs., 11 oz. and measuring 22 inches long.
“Mom, Dad and baby are happy, healthy and enjoying their new addition,” a rep for the band tells PEOPLE.
“I can’t wait to raise a family with her because she’s a great woman,” Followill, 30, told PEOPLE in August.
Caleb isn’t the first King to have a kid. His cousin Matthew Followill welcomed son Knox, 13 months, last April.
