Prince Harry 'disappointed' Kate Middleton with hurtful remarks

Prince Harry has reportedly left his sister-in-law Kate Middleton 'disappointed' with his hurtful remarks, a royal expert has claimed.

Speaking to the Fox News Digital, royal expert Christopher Andersen said Archie and Lilibet doting father, who once shared brotherly relations with sister-in-law Kate apparently disappointed the Princess of Wales after he said “I’d like to mend fences because we just don’t know how long [my father] has to live.”

Andersen spoke to numerous sources for his book "Kate!"

The insiders told the expert, "The final straw came really shortly after the king was diagnosed with cancer, when Harry [essentially] said, ‘I’d like to mend fences because we just don’t know how long [my father] has to live.’ Well, that kind of statement can be very hurtful to somebody who doesn’t really want to consider their own mortality and is battling cancer."

"It was hurtful to Kate as well, I believe," said the expert and added "And, of course, it just ignited this firestorm of speculation about how sick the king really was at this point. And Kate pretty much felt that would be it. She wasn’t going to try anymore. So she has not. And as a result, there has been no chance of any … As a matter of fact, I don’t think we’re ever going to see them make amends. At least it’s not on the horizon now."

He further wrote that the Princess of Wales was "disappointed" with Harry.

About Prince William, the expert said he was "apoplectic" with rage over the remarks.

Andersen also wrote that Kate told William she "was done with Harry."
