However in August of 1997 Princess Diana and her boyfriend at the time Dodi Fayred died from injuries they suffered in a car accident. Most people thought the death was a conspiracy by the British Royal family to get rid of Diana
This conspiracy was followed by accusations of her being pregnant, and she was preparing to tell the world in a large announcement. So her death was planned so that she couldn't tell anyone. The royal family was also allegedly upset about the fact that he wasn't Christian, and that would leave a Muslim heir to the throne.
However it was later found through blood sampling that Diana was not pregnant at the time of her death, and no preparations were being made for a massive announcement.
