It all started innocently enough.

On Aug. 10, country singer Jason Aldean posted a cute photo of himself with his mistress turned girlfriend, Brittany Kerr, and their new bulldog, Manny. The photo was accompanied by the caption: “A little surprise for my girl @brittanylkerr tonight. Her favorite pooch @manny_the_frenchie came to my show in Chi-Town tonite. #loveubaby #surprise.”

However, some fans didn’t seem to appreciate the post, presumably because they still harbor resentment for Aldean cheating on his wife with the former American Idol contestant. Many of his 500,000 Instagram followers wrote some angry comments on the post.

A frustrated Aldean posted a follow-up photo Aug. 11 to address the haters, with 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. Im 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.”

Aldean, 37, filed for divorce from wife Jessica Ussery in 2013. It wasn’t until April 2014 that Aldean and Kerr finally went public together at the CMT Music Awards.

Kerr posted her own photo of the threesome with the caption, “Tonight!!! One of the best nights of my life! I met @manny_the_frenchie such a sweet little nugget #bestboyfriendintheworld #animallove #chunky #butt.”

She received a lot of hate-comments, as well.

At the time of the scandal, Aldean issued a public apology for “screwing up” with the Idol singer.

“The truth is that I screwed up. I had too much to drink, let the party get out of hand and acted inappropriately at a bar,” he said. “I’m not perfect, and I’m sorry for disappointing you guys.”

Aldean and Ussery have two daughters together, Keely, 10, and Kendyl, 5. The high school sweethearts were married in 2001.
