The royals left the Christmas church service at St. Mary Magdalene.
This was the beginning of rumours of a rift between the house of Sussex vs the Cambridge clan.
And we all know how that panned out...
In July, the Cambridges and the Sussexes finally parted ways, with Kensington Palace announcing their joint charity had officially split.
The 'Fab Four' ran the Royal Foundation together, but Prince Harry and wife Meghan Markle, Duchess of Sussex, cut ties with the foundation to pursue their own charitable interests, separate from Prince William and Kate Middleton, Duchess of Cambridge.
