Theyโve been through a lot together, but it appears that Prince William and Prince Harry are not as close as they once were.
The royal brothers will no longer be neighbours as Harry and wife Meghan make the move to their new residence, Frogmore Cottage in Windsor, while William, Kate and their three children remain at Kensington Palace.
But royal aides and friends close to the Princes say that the move is due to a lot of underlying tension.
โHarry knows he will always be in Williamโs shadow and for many years he has felt like a bit of a spare wheel, dragging along behind his brother and Kate,โ a friend revealed to The Express.
โNow he has a life of his own and a family of his own. It is perfectly natural to want to be more independent.โ
However, the source adds itโs not all doom and gloom and this also signals a fresh start.
โThis isnโt the end of a great relationship but the start of something new. Harry and William will always be close, but they donโt have to be twins.โ

According to UK paper The Express, for a long time before Meghan was in the picture, Harry was the third wheel to his older brother and sister-in-law. But now that he is a married man and has a baby on the way, Harryโs priorities are very different.
โItโs now about his wife, his family. Heโs not trying to please anyone else,โ the friend revealed to the publication.
And itโs not just the brothers who arenโt seeing eye to eye โ reports from The Daily Mail reveal that their respective wives are the real reason behind the royal rift and arenโt going to be friends any time soon.
โKate and Meghan are very different people. They donโt really get on,โ the source said.
A royal aide even hinted that Duchess Meghan is the royal equivalent of Yoko Ono saying, โEven The Beatles broke up eventually. The brothers arenโt children any more, theyโre approaching middle age very fast.โ
According to The Sun, Harry and Meghan were originally going to move from their cottage in the grounds of Kensington Palace into one of the main apartments.
โBut there has been a bit of tension between the brothers,โ the source revealed.

This isnโt the first time itโs been reported that Meghan has reportedly clashed with her sister-in-law Duchess Catherine.
โMeghan can be difficult. She has very high standards and is used to working in a Hollywood environment,โ a royal insider explained to The Sun.
โHowever, thereโs a different degree of respect in the royal household and Kate has always been very careful about how she has acted around staff.โ

The Duke and Duchess of Sussex also made headlines when The Mail Online dropped a bombshell that the royal couple have lost three important staff members from their team since their wedding in May. This includes their private secretary Samantha Cohen who had worked with the royals for 17 years.
Royal biographer Robert Jobson also revealed some juicy insider information in Charles At Seventy: Thoughts, Hopes And Dreams, where an insider revealed that Harry had a pre-wedding meltdown and was โpetulant and short-temperedโ with members of staff in the lead up to his big day telling them, โWhat Meghan wants, she gets.โ
