Even if you aren't a royal lover, you've probably watched (or at least heard of) The Crown.
The uber-popular Netflix drama chronicles the life of Queen Elizabeth II (played by Claire Foy), Prince Philip (Matt Smith), and other senior members of the royal family from the 1940s to modern times.
While viewers get an intimate look at one of the most famous royal couples in the world, season one, and especially the new season two coyly dance around rumours that Philip cheated on Elizabeth - but how much of it is true?
In the video above, royal historian Carolyn Harris, author of Raising Royalty: 1000 Years of Royal Parenting, breaks down what really happened on Prince Philip’s solo 1956 trip abroad that caused a royal scandal.
In The Crown, the five-month tour appears to cause serious distance between the couple, showing the Queen finding a photo of another woman in Prince Philip's luggage before he leaves.
It also depicts the Prince and his right hand man Commander Michael Parker away from their wives as they toured for months on end.
So what really happened?
