Why She's Sexy: Kellie Pickler seemingly went from cute to sexy overnight. Soon after fans quit shouting "Pick Pickler" on 'American Idol,' the bombshell introduced a more grown-up look. As she's grown older and gotten married, she's only been more willing to reveal a figure that she clearly takes very good care of. All of this, plus she's not afraid to drink beers with the boys and swear like a sailor. That is sexy!
