Jason Aldean on Relationship with Brittany Kerr: 'Sick of People Judging Me'

The country singer speaks out on relationship with his new girlfriend.

-- Jason Aldean began a relationship with Brittany Kerr while still married in 2012, and when he and wife Jessica Ussery decided to split in 2013, he once again stepped out with Kerr months later, essentially dating the woman with whom he was involved toward the end of his 12-year marriage.

The country star pointed out that most fans and haters don't really know what really happened between him and his ex, and that he's sick of the negative words thrown at him and Kerr for their ongoing relationship.

"So sick of people judging me and @brittanylkerr over things they know nothing about," Aldean, 37, wrote Sunday on Instagram. "I have made mistakes but i am a better person because of it, and wouldnt change a thing."

He continued, "Im happier than i have ever been, so thank u to all the people who support us. We are happy and life goes on. Its time to move on people. #aldeanarmy #oldnews #timetomoveon."

Aldean and Kerr made their first public appearance together in April, hitting the CMT Awards together and walking the red carpet as a couple.

Since then, they haven’t been shy about posting on his relationship. He even surprised Kerr with an adorable pooch.

"A little surprise for my girl @brittanylkerr tonight. Her favorite pooch @manny_the_frenchie came to my show in Chi-Town tonite. #loveubaby #surprise," he wrote.
