Zac BrownZac Brown and his wife, Shelly Brown, 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 Feb. 2. She was born at the couple's Atlanta-area home.

Joni Mason has three older sisters: Justice, 4, Lucy, 2, and Georgia, 1. And if Dad Zac has his way, baby No. 5 won't be far behind.

"We're just gonna keep on going until we get a boy," said Zac, who is one of 12 kids in his family. "If that's 13, then I doubt I'm gonna be able to pull that off, but we'll see."
