Zac Brown and his wife Shelly have a new arrival.

Alexander Frost Brown made his way into the world on Monday, weighing in at a whopping 11 pounds, 7 ounces! Alexander joins his four sisters Justice, Lucy, Georgia and Joni. A few years back, Zac said that though he adores his girls, once he had a boy, he and his wife would get out of the baby-making business.
