We announced back in August that Zac Brown of the Grammy-winning Zac Brown Band was expecting a new baby — and guess what — she’s made her debut!

Joni Mason Brown is the fourth little girl to join the Brown household. Little Joni has three big sisters — Justice, 4, Lucy, 2½, and Georgia Sloan, 16 months.

Zac insists that he and wife Shelly will keep on truckin’ until they can make a boy.

He said:

“We’re just gonna keep on going until we get a boy,”

Zac is one of 12 kids himself, so the ‘keep going til you get it right’ mentality isn’t very far fetched.

The ‘Chicken Fried‘ singer added:

“If that’s 13, then I doubt I’m gonna be able to pull that off, but we’ll see.”

We’ll keep our fingers crossed that you guys get a mini-Zac on the next go-round….which should be in about a year if history repeats itself.

Congrats to the Brown family!
