Julia Roberts Good Genes or Good Docs?!

Julia Roberts' stunning looks over the years proves she's a "Pretty Woman!"

Here is a 21-year-old version of the Hollywood icon showcasing her voluptuous curls playing Vivian in "Pretty Woman" back in 1990 (left). This role cemented her status as one of the greats, and led to other starring roles in movies like "My Best Friend's Wedding" and "Erin Brockovich."
