TMZ has photos of JASON ALDEAN wrapped around and kissing former "American Idol" contestant Brittany Kerr.  This is pretty devastating because, as you probably know, Jason is a married father of two. 

--This happened last Wednesday at a club in Hollywood called The Den.  There's clearly something going on between these two IN the bar . . . however, they did NOT leave together.  Jason slid out of the place with a bunch of dudes. 

(--Here are the photos.  The first three are Jason and his crew leaving the club in a cab . . . but the rest are Brittany and Jason together.)
