The baby weighed in at 6 pounds, 14 ounces. He gets his first name from Luke, whose full name is Thomas Luther Bryan. The baby's middle name, Boyer, is Caroline's maiden name. But he'll be called 'Bo' for short.
Little Bo Bryan is already dressing in good country style. Josh Turner sent him a onesie with a guitar on it, and famed country video director Shaun Silva sent a onesie that says "I Crawl the Line."
