"I knew the tremendous amount of hope the Royal Family invested in Meghan being a success," the author explained in an interview with The Daily Star.
"Hundreds of millions of people of colour were rooting for Meghan, I was rooting for Meghan, being a Jamaican, I was emotionally invested in Meghan’s success. Virtually everybody I know, including my Royal friends, the wider aristocracy, wanted Meghan to be a success. But it quickly became apparent the ride may not be as smooth as everybody had hoped it would be, and it would not be as quite as positive as everybody had hoped it would be."
Going on to explain that the incident which started the rift was in her upcoming book, the author teased: "I can’t repeat it exactly, it’s in the book, but what I can say is, something happened at the very first garden party at Buckingham Palace."
She continued: "We were all absolutely gobsmacked and astonished, we all thought this doesn’t bode well".
Meghan and Harry: The Real Story is set to be released on July 28.
