Meghan has been forbidden by the Queen from wearing the jewelry made famous by Princess Diana.

Her Maj has willingly loaned classic pieces to Princess Diana and Kate in the past, but insiders claim she has been disappointed by some of Meghan’s behavior.

An insider said: “This is a surprising situation that has been going on behind the scenes over the past few months and has caused tension and upset, especially for Harry.

“It is at the discretion of the Queen and trusted advisers which items in the Royal Collection she chooses to loan out and to whom.

“Aspects of Meghan’s behaviour, including before the Royal Wedding, caused resentment with forces within Buckingham Palace.

“To be perfectly honest, the Queen herself was not impressed with some of Meghan’s demands, especially as a new member of the family.”

“As a result, Buckingham Palace has decided that not all items from the Queen’s royal collection will be opened up to Meghan.

“As part of that situation, the Queen informed Prince William that the items from the Royal Collection worn by Princess Diana would not immediately be made available to Meghan.”

The senior source added: “The Queen likes Meghan personally but this is about the hierarchy.

“She is showing that maintaining the correct order and precedence within the family is important.

“Even if Meghan is the most popular woman in the world, she is of a lower rank than Kate.”

Rumours have persisted about whether Prince Harry and his brother, Prince William, had a falling out.

The Duchess was denied the use of an emerald tiara for her wedding, prompting husband Harry to scream, “What Meghan wants, Meghan gets.”

The Queen finally picked a diamond and platinum headpiece for her. According to sources at the time, Meghan “can be difficult” and has “high standards” since she is “used to working in a Hollywood environment”.

There have also been rumors of a feud between Meghan and Kate, which were fueled by the creation of Meghan and Harry’s own Instagram account.
