Zac Brown and his wife Shelly are now the proud parents of a fourth daughter!

The couple welcomed Joni Mason Brown, weighing 7 pounds, 14 ounces, into the family the morning of February 2. She was born at the couple's Atlanta, Ga.-area home.

Joni Mason has three older sisters: Justice, 4, Lucy, 2, and Georgia, 1. And if Dad Zac has his druthers, baby No. 5 won't be far behind. "We're just gonna keep on going until we get a boy," Zac, who is one of 12 kids in his family, told The Boot. "If that's 13, then I doubt I'm gonna be able to pull that off, but we'll see."

Joni will have some company in the playpen when she hangs with her extended Zac Brown Band family. Fiddler Jimmy De Martini's new son Joseph Lance De Martini was born on December 2, 2010.

The year is already off to a great start for the ZBB. Last year's Best New Artist Grammy winners are up for five Academy of Country Music awards. Four of Zac's individual nods are for co-writing and producing the No. 1 hit, 'As She's Walking Away, which features guest vocals by Alan Jackson. (Watch the band perform the tune live in our studio below.) The song is off the album, 'You Get What You Give,' which also features guest artists Jimmy Buffett and bluegrass guitarist Tony Rice.

The Zac Brown Band will hit the road again in March for a long line of shows, including stops in Houston, Baton Rouge and Philadelphia.
