The first sign of the Fab Four fallout between Prince Harry, Prince William, Princess Kate and Meghan Markle was when they had separate Christmas parties and seven months after the Sussex's wedding.
The Sussexes and now-Waleses had two separate Christmas parties in December 2018.
At the time, it was reported how Meghan and Prince Harry opted to stay with at the Queen's Sandringham estate "packed like sardines" rather than stay with William and Kate in their 10-bedroom home nearby.
