Diane Keaton has been a well-known actress for almost five decades now. She originally came to fame as Woody Allen's muse in 'Annie Hall', but her first television appearance was on a commercial for an anti-perspirant. Fast forward to the present and Diane is still playing lead roles in romantic comedies. In her latest movie, playing opposite Mandy Moore entitled "Because I Said So", she plays an over-bearing mom who proves that you can still find love at any age. What's most admirable about Diane is that in an industry that almost demands plastic surgery and Botox, she has refused both. She is living proof that beauty can be achieved naturally. L'Oreal believes in her so much that she is now appearing in both print and television ads for their calcium-fortified skincare products. Diane has also proved to women that you don't necessarily need a man to have a fulfilling life. Although she has been romantically linked to both Woody Allen and Warren Beatty, Diane has never married, but she is a single mom to two children whom she adopted at birth. She truly is an ageless beauty!
