It's been almost two years since the country singer was spotted getting cozy with another woman while still married – and he says it's about time everyone move on from the drama.
After posting a snapshot of his now girlfriend, Brittany Kerr, with whom he was photographed in 2012, on Instagram Sunday, Aldean's followers unleashed their fury in the comments.
And before long, the father of two, who filed for divorce from wife Jessica Ussery in 2013, came to Kerr's defense with a second Instagram of the words, "You know my name, not my story. You've heard what I've done, not what I've been through."
Aldean, 37, added an explanation – and an update on his life with the American Idol alum – in the caption.
"So sick of people judging me and @brittanylkerr over things they know nothing about. I have made mistakes but I am a better person because of it, and wouldn't change a thing," he writes.
"I'm happier than I have ever been, so thank u to all the people who support us. We are happy and life goes on. It's time to move on people. #aldeanarmy #oldnews #timetomoveon."
In March, PEOPLE confirmed Aldean and Kerr were dating.
