Kate Middleton will reunite with Prince Harry after she reportedly tried to stay out of his and Prince William’s rumored feud.

The Duke and Duchess of Cambridge and the Duke and Duchess of Sussex are set to reunite over the weekend for the annual Royal British Legion Festival of Remembrance at the Royal Albert Hall. Prince William, Middleton, Prince Harry and Markle have not publicly attended an event together since Trooping the Colour in June.

According to Express, it would be the first time in months for Prince Harry and Middleton to reunite for an official engagement. Prince William’s wife and brother have become close friends over the years with Prince Harry saying that Middleton is the “sister he never had.” Many are looking forward on how the sister- and brother-in-law would interact at the event.

Just recently, a source told Us Weekly that Middleton was worried of Prince Harry and Markle following their emotional interview with ITV. Middleton reportedly hates seeing them “so miserable.”

There are rumors that Prince Harry is feuding with his older brother Prince William over Markle. Middleton was affected with the controversies, but she wanted to remain in the background and stay out of the drama.

An insider claimed that Middleton called Markle after learning about her and Prince Harry’s candid interview in a documentary. However, another insider said that it was unlikely because while Middleton sympathized with her sister-in-law, she wanted to keep herself out of the situation.

“Kate has enough on her plate looking after three kids and fulfilling royal duties. She barely has a moment to herself and tries to avoid drama and conflict at all costs,” the source said

Prior to Markle joining the royal family, Prince Harry was very close to Prince William and Middleton. The three royals attended engagements together and were inseparable that they were called “the royal trio.” But he has never been seen as often with the couple after he married Markle.

Despite Prince Harry’s issue with his brother, an insider said that he would not let his relationship with his sister-in-law be affected with his rumored feud with Prince William. Earlier this year, Prince Harry joined Middleton at Anzac Day service at Westminster Abbey. Their joint appearance made several royal fans happy with one saying tha the royal in-laws were a “beautiful duo.”
