Time to get a bigger tour bus! Zac Brown of the Zac Brown Band has welcomed a fifth child. He and wife Shelly are the parents of a little boy — their first son! The band shared the happy news earlier today (May 8).

Zac & Shelly Brown are pleased to announce the arrival of Alexander Frost Brown! Born May 5, 2014,” the band’s official Twitter announced alongside a photo of the happy couple. They announced they were expecting again back in November.

Following Alexander’s birth, his parents released an official statement giving the new guy’s measurements — a whopping 11 lbs., 7 oz. and measuring 22.5 inches long. Big boy Brown!

Alexander joins four older sisters: Joni Mason, 3; George Sloan, 4; Lucy; 5; and Justice, 7. We imagine Zac’s pretty pleased to have another boy finally in the mix seeing as he told People back in 2011, “We’re just gonna keep on going until we get a boy.” Mission accomplished.

Zac head outs with his Atlanta-based band at the end of this month on their Great American Road Trip tour. No word yet on if the little ones will tag along as the ultimate groupies but we’re thinking newborn Alexander will probably be kicking it with Mom back home.
