Luke Bryan, 31, and his wife, Caroline, 28, welcomed their first child, Thomas Boyer Bryan at 11:34 a.m. on Tuesday at a Nashville area hospital.
Bryan said he was "over the moon" to meet his new son, who weighed 6 lbs., 14 oz., and added: "Everyone is doing great! My fishing buddy is finally here!"
"I thought being on stage was an amazing feeling, but there is nothing that can top watching my wife bring our son in to this world," the singer tells PEOPLE. "There is no way I would have missed this for anything."
The baby gets his name from his father, whose formal first name is Thomas. Boyer is mother Caroline's maiden name. But his parents will call the boy "Bo," Bryan said.
Bryan and his wife met in 1998, when the two were students at Georgia Southern. They married on Dec. 6, 2006.
Already, Baby Bo has scored some great country swag from the likes of singer Josh Turner, who sent a onesie with a guitar on it, and country video director Shaun Silva, who gave the little guy an "I Crawl the Line" onesie.
