At approximately 1:28 a.m., the pedestrian, Albert Kennedy of Vincennes, Ind., "walked out into the middle of the roadway" and was struck by Aldean's bus on the northbound lane of US 41 North, the police report said.
Knox County Sheriff Michel Morris confirmed that Aldean, 36, was on the bus at the time of the accident.
When the coroner arrived on the scene, he pronounced "the individual deceased from trauma to the head and chest," according to the police report.
The "My Kinda Party" singer took to Twitter to share his condolences for Kennedy and his family.
"With a heavy heart, I'm sad to say that a man passed away last night after stepping out in front of my bus in Indiana," he tweeted. "In all the years I've been touring and all the miles we've driven, nothing prepares you for something like this to happen. I'm praying for Albert Kennedy's family and friends today and ask that you do the same."
An investigation into the accident and death are underway.
According to the singer's website, he had just raised more than $575,000 in support of Susan G. Komen this past Friday in New Orleans, LA.
"Like pretty much everyone I know, I've lost someone I love to breast cancer and I don't want anyone else to have to go through that," he said on stage during his eighth annual "Concert for the Cure."
Aldean is a three-time Grammy Award nominee and multiple CMA Award winner.
It's been a tough year for Aldean. The singer and his ex-wife Jessica Ussery filed for divorce in April after he admitted to acting inappropriately with another woman.
