Jason Aldean's touring life is a little different these days. He's replaced the liquor bottles with baby bottles, and there's much less partying going on overall thanks to his infant son, Memphis.

“Used to, when you walked on our bus there was liquor bottles," Aldean tells Entertainment Tonight in a recent interview. "Now, there’s like baby bottles and empty formula cans and toys all on the floor. It’s crazy.”

The singer is about to welcome even more bottles and diapers with the addition of his fourth child, a girl, arriving later this year. This marks Aldean's second child with wife Brittany. He has two older daughters, Keeley and Kendyl, from a previous marriage.

The singer has been getting used to his new reality since Memphis was born last December. As he describes his tour now: “It’s got two cribs in the bus, which I never in the early days of my touring career thought I’d ever do that, but it’s different,” he previously told People. “It’s a lot different now than it was the early part of my career. Things are settled down.”

“I got playpens sitting outside my bus on college football. I’m watching college football and [son Memphis] is in the playpen. That was never a thing early on, so it’s cool,” he adds.

Aldean told Taste of Country Nights back in May that he appreciates being able to take his little boy out on the road with him, something that wasn't possible when his two older children were younger.

"Back when [my daughters] were born, when I was touring I was on one bus with my whole band—there was 12 of us on a bus," he explained. "So I wasn’t in a position to be able to carry them out a whole lot back then."
