Aldean already has three children.
(Nashville, TN) -- Jason Aldean says he's ready for a second baby with wife Brittany right now.
The country crooner tells "Taste of Country Nights" they've got one in diapers and on formula right now, so they might as well "knock it out."
Aldean has two older daughters from a previous marriage, and he says he wants to have another baby closer to Memphis' age.
