See Stunning Vintage Photos of Grace Kelly, On-Set and Off

Before she became the Princess of Monaco, Grace Kelly was already one of the biggest names in the world. Born in Pennsylvania, Kelly moved to New York City at 20-years-old to pursue an acting career. Soon after, Kelly was Hollywood's most in-demand actress, appearing in major films such as High Society, To Catch A Thief, Dial M For Murder, and Rear Window, the latter of which cemented the actress's status of an on-screen fashion icon with a memorable black-and-white dress that has gone down in cinematic style history. Of course, it was hardly the only time Kelly looked glamorous on film. In honor of her birthday, take a look back at some of her most stunning photos, on-stage and off.
