It's a Boy for Jo Dee Messina!

Noah Roger Deffenbaugh was born at a Nashville-area hospital at 1:01 p.m. on Monday, weighing in at 6 lbs., 15 oz.
Ready for Noah's arrival at home is a handmade crib and changing table built by his woodworker dad, who owns Deffenblaster Enterprises, which builds custom road cases.
Messina, 38 – who wed Deffenbaugh, 28, in October 2007 – told PEOPLE.com recently that the pregnancy was a welcome surprise.
"We knew we wanted to have kids, but we just said, 'Whenever it happens, it happens.' And it happened!" she said. "We were both surprised at first. It's such a lifestyle change. But then we're like, 'Wow, we're going to be parents!'"
The singer also said she planned to take her new son along when she begins a solo tour this April to promote her upcoming album, Unmistakable.
"But I'm like, 'How do you do that?'" Messina said. "Who rides where? Band? Crew? Family? What safety devices do you need? I might grab one of the other singer moms like Sara Evans or Martina McBride and say, 'Help me!'"
