I think when you take away the makeup, the wardrobe, the carefully selected angles, the selection of only the best photos, the hairstylist...what you are left with in most cases when it comes to these celeb babes is a real person, who is something less than a perfect bombshell at any given moment. Most of this beauty/glamor stuff is show biz trickery.
I dunno, I think my wife is a bombshell from all angles at all times. She is one of those women who look better without make-up than with it.
