It's possible that the family reunion could be a bit awkward, especially since some of Harry's royal cousins were recently seen hanging out with the outspoken TV presenter, Piers Morgan.
Princess Beatrice and Princess Eugenie, who are known to be very close to Prince Harry, were spotted meeting with Piers and other friends, including singer-songwriter James Blunt, at The Princess Royal pub in London's Notting Hill neighbourhood.
They were seen laughing and joking with the controversial presenter as they left the venue. This move seemed to have snubbed the Sussexes, and Harry was reportedly less than impressed by the development.
Despite this apparent rift, a royal expert has predicted that Prince Harry "won't burn the final bridge" with his cousins.
This suggests that even though the relationship between Harry and the princesses may be on shaky ground, he is unlikely to cut all ties with them completely.
After all, family is still family, and it's important to maintain some level of cordiality, especially in the public eye.
