It would seem that Prince William and Prince Harry's already fractured relationship has descended even further down an ugly tense path, as rumours the two brothers won't even stay under the same roof at Balmoral begin to swirl around the pair.
A palace source has revealed the royal siblings - who were once as thick as thieves - won't be anywhere near each other, and the tension is largely due to their wives frequently butting heads.

Speaking with Vanity Fair, a source informed the publication that Prince William and Kate Middleton were booted from the castle and moved instead to the cottage on the grounds of the large estate.
What's more, the source dished that the palace aides had to make sure the Duke and Duchess of Sussex's visit to the Queen's castle in Scotland did not coincide with the Duke and Duchess of Cambridge's, so as to avoid a potential row between the foursome.
"It can get quite busy at what they call 'the big house', and it's not especially relaxing even though it's a holiday," the source began.
"There's a daily routine which evolves around mealtimes, several outfits changes every day, sometimes five, and the Queen likes everything to run like clockwork.
"The focus is on being outdoors and in the countryside walking, grousing, fishing and hunting."

According to the Daily Mail, the feud began when Prince Harry took the drastic step of reading the riot act to his brother and sister-in-law when he felt they weren't supporting Meghan Markle ahead of their royal wedding last year.
Prince Harry then royally peeved off William and Kate when he announced he would have "two children maximum", on account of the environmental impacts of a big family - despite Prince William and Kate Middleton happily parenting three children, Prince George, six, Princess Charlotte, four, and Prince Loius, one.
