Zac Brown Band frontman Zac Brown and his his wife Shelly are parents for the fifth time after the arrival of their first son, Alexander Frost Brown.

The baby made his entrance into the world on Monday (May 5) and he certainly was a big boy. He weighed a whopping 11 pounds, 7 ounces. Brown explained that the couple's planned homebirth had to be transferred to a medical center for precautionary reasons, adding:

"We couldn’t have asked for a better and more supportive team to allow us the natural delivery we wanted of our baby boy. Alexander Frost Brown 11lbs. 7 oz."

Alexander was welcomed by his four sisters, Justice (7), Lucy (6), Georgia (4) and Joni (3). However, he will definitely be the only boy; Brown, who is one of twelve siblings, admits that he's done having kids and is more than ready to go under the knife. “I’m ready, I’ll go under the knife whenever the time will allow now," he testifies.

The Brown household will certainly be bustling, especially as Brown and his band leave for tour later this month.

The Grammy-winning band will load up the bus later this month for the Great American Road Trip Tour. It's not just any old tour; it includes sold-out stops at Fenway Park in Boston. ZBB will also headline Wrigley Field this summer.

Congratulations to the Brown family on their healthy baby boy!
