Princess Anne was said to have been in a relationship with Andrew Parker-Bowles before she married Captain Mark Phillips and the pair are still close friends now
Princess Anne
For those who are familiar with season three of Netflix’s The Crown, you will be aware of a storyline that sees the then Prince Charles grow close with Camilla Shand, while Princess Anne becomes entangled with her on-and-off boyfriend, Andrew Parker Bowles.
As you may expect, the story has been heavily dramatised for the sake of the programme – but there does lie a grain of truth behind it. It is known that The Princess Royal and Major Andrew Parker Bowles were incredibly close and bonded over a shared interest in horses.
It is however said that their courtship did not overlap with King Charles and Camilla’s budding relationship.
