Princess Olga Romanoff is a royal rebel that defies all the rules of a “typical” noble.

The energetic, “potty mouth” Russian princess is known to use quite a colourful array of swear words and live her life outside the royal norms.

A descendant of the Russian Romanovs and cousin of the late Queen Elizabeth, she has starred in multiple reality TV series and has openly talked about her life to the public. She is set to star in a new reality show called The Big Celebrity Detox (working title) airing in 2023, reports British media.

But before it hits our screens, here are a few things to know about the unique princess – and how she almost ended up marrying King Charles.

Her royal background

Princess Romanoff, 72, is a cousin of Queen Elizabeth. Her father was Prince Andrei Alexandrovich, who was the nephew of former Russian emperor Tsar Nicholas II, who in return was the cousin of King George V, grandfather of Queen Elizabeth and Britain’s king from 1910 to 1936.

Romanoff’s link to Britain was set in stone when Prince Andrei fled to the country after the Bolsheviks killed the Russian royal family in 1918.

The prince and his family members who escaped spent the rest of their lives in exile while being dependent on their British relatives. Romanoff’s mother was Nadine McDougall who was a member of the Scottish flour mill family. Romanoff’s grandmother’s house was the same Frogmore Cottage that was home to Meghan and Harry before belonging to Princess Eugenie and her family, as per Kent Online.
