The big news comes just about a month after Rhett told ABC News that he, his wife, Lauren, and his daughters, Willa and Ada, were looking to grow their happy family.

\"If we stopped having kids now, I know I'd wake up at 45 and go, 'We should have had five more,'\" he revealed.
Rhett added, \"Because I really do want to be able to sit at a Thanksgiving or Christmas table with the most gigantic family on the planet.\"
Well sir, you are on your way!
