Prince William and Prince Harry are reportedly the two members of the royal family who had a falling out, not their wives Kate Middleton and Meghan Markle.

Middleton and Markle's feud has been a popular topic since the latter married Prince Harry last year, with many speculations claiming the two just don't get along. However, royal filmmaker Nick Bullen told Fox News that the real rift is between Prince Charles and Princess Diana's two sons, who recently announced the separation of their households.

“It’s actually that William and Harry have had a rift,” Bullen, who claimed that the "suggestion" of a rift between Princes William and Harry came from a "well-placed" source, said. “All brothers fall out, all families fall out. Their fallout at the moment is becoming public.”

Bullen, who has worked closely with Prince Charles, also revealed his thoughts on why Middleton and Markle's "feud" completely eclipsed Prince William and Prince Harry's fallout. He said that a fight between the two duchesses seemed to be a "much sexier story" for the media.

“Let’s have these two super glamorous women — one British, one American, one an actress, one sort of an English rose. Let’s put them against each other,” he explained.

As for Prince William and Prince Harry's so-called rift, Bullen said that it is completely normal for the two princes to grow apart as they become adults and start their own families.

“I think people don’t want to think about that with these two boys," Bullen continued. "These are two boys who lost their mother [Princess Diana] at a really early age, and the fairytale is that they are closer than ever and need each other, and I think that’s probably true. But equally, they are two grown men in their 30s, starting their own families, different wives. They are moving to different parts of the country, different duties.”

However, he said that the "rift" between the two brothers may not last long because their father, Prince Charles, and grandmother, Queen Elizabeth II are reportedly “working incredibly hard to try and make sure everybody reunites.”

Back in November, a source told Us Weekly that there was no truth to the reports that Markle and Middleton do not get along. According to the insider, the "feud" is just being exaggerated b the media. Though the two duchesses may not be best friends, Middleton and Markle reportedly do not hate each other like what many have claimed.
