Upon hearing that the Queen would join them for lunch after attending a church service at Windsor Castle, Harry asked Meghan in the car ride there if she knew how to curtsy to Her Majesty and it's thanks to Fergie, as she calls Sarah, that she quickly learned how to do a "very deep curtsy".

"I learned it very quickly, right in front of the house. We just practiced and then walked in." she recalled. She later added: "Fergie ran out and said, 'Do you know how to curtsy?' Apparently, I did a very deep curtsy, I don't remember it, and then we sat there, and we chatted."
During the two-hour chat, Meghan also revealed that she knew Princess Eugenie before dating Prince Harry and that they were "friends with them as a couple".
During the sensational interview, the couple spoke about a range of topics including Meghan's mental health, accusations the royal family was racist and the full extent of Harry's fractured relationship with his father Prince Charles as well as reaching out to the Queen when Prince Philip was admitted to hospital.
