His two young daughters aren’t even old enough to drive, so why does Jason Aldean already have grandbabies on the brain?

The country megastar tells Billboard magazine he hopes his new gig as stadium headliner leaves a good legacy for his future grandchildren.

“We may [play stadiums] for two years, we may do it for 10 years, I don’t know,” he says. “My grandkids will look back at the pictures of us playing stadiums and go, ‘Damn, my grandfather was actually pretty cool.’”

The article estimates that Jason’s Burn it Down Tour is part of a new record-breaking year for stadiums.

Jason’s first stadium concert in Cincinnati grossed more than $2.6 million alone. He brought in an addition $10.2 million more from four additional stadium shows in Cleveland, Pittsburgh, Philadelphia and Washington, D.C.

According to Billboard, artists will perform more stadium shows this year than any year since 1994.
