The close relationship between Kate Middleton and Prince Harry has reportedly been shattered due to feelings of 'mistrust' and 'betrayal'.

Prince Harry and Kate Middleton were once extremely close, with Harry often spending time with Prince William and his wife.

The Duke of Sussex even described Kate as "the sister I've never had and always wanted." However, their once strong bond was shattered following the release of Harry's tell-all memoir, Spare.

In the book, Harry made several accusations against members of the royal family, including Kate. He claimed the Princess of Wales was "on edge" when he married Meghan Markle because she was now "going to be compared to, and forced to compete with, Meg."

He further asserted that a conflict regarding the bridesmaids' dresses resulted in Meghan being found "sobbing on the floor." Both William and Kate were said to be hurt and feeling betrayed by these claims, while Harry received backlash for launching such intimate accusations, fully aware that the royal family would refrain from addressing them publicly.
