Prince Harry ‘hit hard’ by Kate Middleton cancer battle as she and William are ‘going through hell’

Prince Harry has been “hit hard” by his estranged sister-in-law Kate Middleton’s cancer diagnosis, according to a royal author.

The Duke of Sussex, 39, on Tuesday touched down in London to celebrate the 10th anniversary of the Invictus Games.

Later that day, Harry’s reps confirmed to The Post that he will not be meeting up with his estranged father this week due to the King’s “full” schedule.

What’s more, the rest of the royals have made no plans to see him during his brief visit to London, which includes the Prince and Princess of Wales.

“Harry would love to reconnect with Kate,” Christopher Andersen, who penned “The King,” told Fox News.

“They were once extremely close, and Harry was hit hard by the news of her cancer diagnosis, which he learned about just the way the rest of us did, via Kate’s shocking video.”

“Unfortunately, it doesn’t appear [Prince] William is willing to let his brother anywhere near his ailing wife,” he added.

Andersen said there has been “too much drama” between the two camps that has caused “lingering bitterness on everyone’s part.”

“The chances of even a meeting between Harry and the rest of the royal family, much less some sort of reconciliation, seem extremely slim,” he added.

In a further blow to the exiled royal, Harry was reportedly forced to check into a hotel room after not being offered a bed at any royal residences peppered across the country.

He also won’t be seeing King Charles while in the UK. Harry’s spokesperson said the monarch’s schedule is too full, as a royal expert also claims Harry had “certain demands” if they met.

Anderson’s comments come just days after Kate and William’s close confidante Amaia Arrieta sensationally claimed that the pair are “going through hell.”

“I’m heartbroken at the moment, I think they are going through hell, I hope they will be back. It’s really personal,” Arrieta, who has worked as a stylist for the Prince and Princess of Wales’ three children since Prince George was a baby, told the Telegraph.

Middleton, 42, is in the thick of her cancer treatment following her diagnosis in March.

She’s not the only royal dealing with health woes, as King Charles, 75, revealed his cancer diagnosis in February, while Sarah Ferguson, the Duchess of York, announced her battle an aggressive skin cancer in January.
