With the royal wedding happening this weekend, much ado has been made about Meghan Markle being an actress and marrying into royalty.
Of course, she isn’t the only actor or actress to marry into royalty or nobility. Well cited examples include Grace Kelly marrying Rainier III, Prince of Monaco, making Grace Kelly a princess. The two were married from 1956 unti her death in 1982. And there was Rita Hayworth, who became a princess when she married Prince Aly Khan, who were married in 1949 and divorced in 1953.
But I started wondering was there anyone else? I found a few other actors who were married to royalty or nobility, though some titles have been up for debate:

Actor Donald Cook (unable to find a photo together with wife)
Donald Cook and Princess Gioia Tasca di Cuto (1937 to 1961): Actor Donald Cook was married to Princess Giovanna Mastro – Giovanni Tasca Di Cuto from 1937 until Cook’s death in 1961. I can find little on Princess Giovnna, except that the two lived in Long Island in the 1940s and also had a home in Connecticut. An April 1971 newspaper called Gioia Cook the great-granddaughter of Prince Niccolo of Sicily. According to a 1966 newspaper, calls Gioia a “former” royal and calls her Gioia Cook. It seems Donald Cook did not take up a title as other stars did. After Donald Cook’s death, Gioia owned a restaurant called Leopard.
