Country Crooner Zac Brown has a tiny new band mate.

The Zac Brown Band front man, 32, and wife Shelly added a baby girl to their brood on Wednesday.

Born at the couple's home near Atlanta, Joni Mason Brown weighed in at 7 lbs 14 oz, according to reports. She joins Justice, 4, Lucy, 2, and 1-year-old Georgia.

It's one more thing for the singer to celebrate; just the day before he received nine Academy of Country Music nominations, and his band is up for four awards at the February 13 Grammys.
