9. Nine is his lucky number.

The number nine was Jason Aldean's baseball jersey number in high school, and he's called it his lucky number ever since. His other lucky number is three, because that was the jersey number he wore before high school. These days, his daughters are beginning to get into athletics, and one of them landed No. 3 on her softball team. Aldean says he chose three because that was Atlanta Braves's infielder Dale Murphy's number when he was young.
