Prince Harry and Prince William shared a tight relationship. Following the death of Princess Diana, it had since appeared that they only had each other growing up.

The close ties between the royal siblings continued to become more apparent in recent years. Even after the Duke of Cambridge married Kate Middleton, the Duke of Sussex still stayed with them. This is why he reportedly has a close bond with his niece and nephew, Princess Charlotte and Prince George.

However, the same could not be said about his relationship with Prince LouisFinding Freedom claims that he spent very "little time" with the youngest Cambridge Prince because of the alleged feud between the Wales Princes, according to the Daily Mirror.

Prince Harry used to live near the Cambridges. It makes total sense why he could spend "a lot of time" with Prince William's two elder kids.

But, by the time Prince Louis arrived in 2018, things were no longer the same between the royal siblings. Authors Omid Scobie and Carolyn Durand wrote in their Sussex-centered book that the royal-born Princes "barely" spent any time together after the summer of 2017.

Finding Freedom adds that the tension between them stemmed from the future King being "less than welcoming" to Meghan Markle, according to Cosmopolitan. The Duke of Cambridge reportedly encouraged his brother to take "as much time as" he needs to know more about the then-Suits actress, to whom he referred to as "this girl. While it was out of good intentions, the Duke of Sussex took it as an offensive remark, thinking that it was "incredibly snobby."

Following the remarks, the biography states that this has since caused a distance in Prince Harry and Prince William's relationship. As a result, the Duke of Sussex spent less time with the children. However, Scobie and Durand argued that the invites from the Cambridge couple first "dried up."

To date, the Duke and Duchess of Sussex are staying in their new mansion in the United States. They relocated to Meghan Markle's home country after they officially exited the British Monarchy.

It remains unclear when they will return to the United Kingdom. But, several royal experts believe that the Sussex household will fly back to Prince Harry's home country next year.

As for the Wales Princes' relationship as brothers, speculations have continued to develop that they are still in a "feud." Nevertheless, some reports claimed that they are already communicating, especially after Princess Diana's birthday last July, as well as her death anniversary last month.
