Grace Kelly and Prince Rainier of Monaco
Anyone who's seen Grace Kelly in Alfred Hitchcock's "Rear Window" or any of her other films knows she was a beautiful, classy actress. But did you know she was also royalty?
She was already a princess of the silver screen, and when she said "I do" to Prince Rainier of Monaco in 1956, she became the real thing. We're talking about more than just a title -- Princess Grace retired from acting to see to her royal duties, and a law was passed in Monaco making it illegal to screen any of her films in order to protect her royal image.
When Grace Kelly became royalty, she had a princess-worthy wedding to prove her status. All 3,000 of Monaco's citizens turned up to see her marry their prince, and her wedding was shown in movie theaters in the U.S.
