Back of Bella Donna: Diane Keaton Mix some eccentricity, a self-deprecating sense of humor, intelligence, wit, along with a slightly reclusive personality and some nervous energy, and you've got Diane Keaton through and through. The 63-year-old actress, who first gained acclaim in the 1970s with roles in The Godfather, along with a string of Woody Allen flicks, was actually born Diane Hall. Since there was already a registered actress with the same name, she chose her mother's maiden name, Keaton, as her professional moniker. Known for starting a unisex clothing trend in the late 70s, as well as her trademark of wearing accessories like gloves, hats, and colorful round glasses, the actress typically styles her hair in a long straight bob.

I believe in repetition. That's why I like saying 'we're worth it, we're worth it, we're worth it, we're worth it, we're worth it, we're worth it.' And don't you dare forget it because you're worth it." View 10 Photos › Wearing a bun in Love and Death, 1975. Photo courtesy of At at the 1976 Academy Awards. Source Annie Hall, 1977.
