Prince Harry had a close relationship with Prince William and Kate Middleton but when Meghan Markle came into the picture, the bond between the trio was never the same.

TLC’s “Kate v Meghan: Princesses At War” documentary explores the rumored feud between the young royals and suggest William and Kate may be upset with Meghan for creating distance in their relationship with Harry.

Editor of Majesty Magazine, Ingrid Seward revealed that before Prince Harry began dating Meghan, he would spend a majority of his free time will William, Kate and their children.

“He was very much a part of their family. Then suddenly he meets Meghan and he falls in love and he’s off. So he’s sort of suddenly out of their lives and there may have been some resentment,” she explained.

Meanwhile, other royal experts believe the Duke and Duchess of Cambridge are unhappy with how much Harry has changed since getting married.

“Everything I hear is that Harry is completely beguiled by Meghan and completely enthralled to her, and has changed considerably. People do change when they get married,” Lady Colin Campbell noted.

However, the documentary suggests Prince William and Kate don’t believe Harry has changed for the better since meeting Meghan.

Despite what may or may not be going on behind the scenes, while in public, the two couples appear to get along and enjoy each other’s company.
