Louis Ducruet of Monaco
Louis Ducruet is also not officially royalty, hence not having the title. He is actually the love child of his mother and her bodyguard! He is still technically 13th in line to become king, but has no official title. If you want to be an official princess you might have to look elsewhere.
Princess Maria-Olympia of Greece and Denmark
Princess Maria-Olympia is the oldest child of Pavlos Crown Prince of Greece and Denmark and Marie-Chantal making her the crowned princess of both countries. Not bad, huh? She is only 22 years old and is beginning a modeling career. There were rumors of her being romantically involved with Prince Harry, and we wonder if she will snag a wedding invite or not. We shall see!
