Today, Angelina Jolie celebrates her 38th birthday, and we want to know — what's her superwoman secret? From devoted mom of six to critically acclaimed actress and director to tireless humanitarian activist, we're taking a closer look at one of Hollywood's most celebrated — and beautiful — actress's red carpet style evolution. Since Angelina has grown up in the public eye, we've seen her morph from gangly girl in her teens to gothic princess in her 20s through motherhood and her relationship with Brad Pitt. The current Angelina impresses us regularly with her affinity to thigh-high accented Atelier Versace gowns (her now memorable Oscars 2012 appearance was not her first foray in leggy territory), slinky Jenny Packham numbers, and classically chic Ralph & Russo creations.
