Jason Aldean was in California and went to a bar on Sunset Strip where TMZ camera's caught him getting close and personel with someone who ain't his wife!! In fact it's Bittany Kerr who was on American Idol at some point.. UH OH.. Jason did leave with the guys he came with and not Brittany.. But he's probably got a lot of 'splainin to do!!   He issued a statement that said:

Hey Guys – I wanted to talk to you directly, so you were hearing the truth from me and not just reading allegations made about my personal life on gossip web sites.  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. I'm not perfect, and I'm sorry for disappointing you guys. I really appreciate being able to work through this privately with my family and for all your continued support.
