is apologizing to his fans after photographs of the country singer appeared online over the weekend.
Aldean – a married father of two – was photographed cozying up to season 11 American Idol
contestant Brittany Kerr at The Den in West Hollywood on Wednesday night, TMZ reports.
The "My Kinda Party" singer, 35, who has been married to his high school sweetheart Jessica Ussery since 2001 and has two daughters Keeley, 9, and Kendyl, 5, issued an apology to his fans via Twitter
"Hey Guys – I wanted to talk to you directly, so you were hearing the truth from me and not just reading allegations about my personal life on gossip web sites," he wrote.
"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. I left alone, caught the bus to our next show and that's the end of the story. I ultimately ended up embarrassing my family and myself," he wrote.
"I'm not perfect, and I'm sorry for disappointing you guys," he continued. "I really appreciate being able to work through this privately with my family and for all your continued support."
Aldean recently earned a CMA nomination
for entertainer of the year.
