Brittany Kerr Returns to L.A. Bar Scene ... without Jason Aldean

Brittany Kerr went back into the danger zone Tuesday night  ... the center of the Hollywood bar scene ... only this time, the former "American Idol" contestant was spotted with a man who WASN'T wearing a wedding ring.

No word on who the mystery dude is ... or how they know each other ... but as long as he's not a married country singer with two kids at home, shouldn't be a problem.
