Renowned for her elegance and beauty, Academy Award-winning actress Grace Kelly met her future husband, Prince Rainier III of Monaco, during a photo shoot at the Cannes Film Festival. The rest is history - the two were engaged by Christmas and married in April 1956. Kelly gave up acting when she became a princess. She had three children with the Prince before her tragic death in a car crash in 1982. She was only 52 years old.
