Zac Brown & wife Shelly welcome their new baby girl, Joni Mason Brown, early this morning. Joni weighed in at a healthy 7 pounds 14 ounces and joins her 3 older sisters, Justice (4 yrs. old), Lucy (2yrs. old) and Georgia (1 yr. old). Zac is currently on break and can enjoy fatherhood before heading back out on the road in March on Kenny Chesney’s Goin’ Coastal Tour.
