Born Oct. 3, Boone is the couple's first child. Eric admits fatherhood has been beyond anything he could have ever imagined. "Everybody always tells you what an awesome and unique experience being a parent is," he says. "But words can never do the feeling justice. The way our life changed in that 24-hour period alone after he was born -- just by putting a little boy in the house --was awesome."
But while Eric may be getting in touch with his softer side for the first time, now that he's a dad, don't expect his notoriously rockin' music to change too much. "I can promise you this: I'm not going to be writing lullabies at any point in time, unless they're like bad-ass, kick-ass lullabies," he tells The Boot with a laugh. "There's maybe a market for that out there somewhere!"
Still, we're betting Boone will find his way into some of Dad's lyrics. "I've always made music that was representative of real life," says Eric. "Life doesn't get more real than having a newborn at home."
Eric and Katherine will spend their baby's first Christmas at home. The country star kicks off his headlining Blood, Sweat & Beers Tour on Jan. 19. See his concert schedule here.
