Last year, Meghan and Harry's decision to move over 40km away from Kensington Palace ignited the royal rift rumours.
In June this year, the Sussex royals' fueled the rumours further when they split from the Royal Foundation charity shared with William and Kate.
However, according to the Daily Mail, royal insiders claimed that there was no royal rift and insisted that the two royals were just "very different people."
"While there are some tensions behind the scenes, Kate is pretty unflappable and nothing has become bad enough to make Harry and Meghan want to move out," a source told the publication.
The insider said that the decision to move away from Kensington Palace was purely logistical, and not tied to any drama with the Duke and Duchess of Cambridge.
"People are genuinely pleased to see them so happy. The truth is that there simply isn't enough room at Kensington Palace for them and I know they have been looking at Windsor as a possibility since before the wedding."
The two Duchesses were recently spotted laughing together at Wimbledon, and have only grown closer since the royal wedding, according to new reports.
