Country music star Zac Brown can finally add a boy to his brood of kids - his wife Shelly is expecting a son after four girls. The couple's daughters, aged from two to six, will welcome a baby brother next year (14), according to a tweet from Brown's bandmates in the Zac Brown Band. They announced the news on Thursday night (07Nov13), writing, "BabyBrown Update! Please help us congratulate Zac and Shelly as they welcome their 1st baby BOY this spring!" Bandmate Clay Cook recently told Country Weekly magazine that he believes the Browns will stop making babies when they have a son, stating, "I think the deal is, if they have a boy, they're gonna quit."
