The bombshell is a creature at one with her sexuality -- a lady, never  a tramp, who uses her feminine wiles to seduce, control and if she so chooses, destroy. She'll easily walk the fine line between good girl and trashbag and openly flirt with the dichotomy of Madonna and whore -- and I'm not talking about that whore, Madonna. The bomnbshell is not merely a pretty face or a rockin' bod -- she's a force to be reckoned with. It takes a little work, but anyone can learn the art of bombshelling. Just take a tip or three from the  iconic bombshells of yore in these twelve classics films.
