Meghan Markle's pre-wedding clash with the Queen

Meghan Markle was labelled 'difficult' by the Queen when she pulled Harry aside and had words with him over Meghan's choice of the tiara for her wedding it has been revealed.

In a book written by reporter Richard Jobson, it is revealed that Prince Harry said "What Meghan wants, Meghan gets," repeatedly to royal staff ahead of the wedding.

So when the couple was told that Meghan wasn't allowed to wear the tiara of her choice, Prince Harry "hit the roof."

Meghan wasn't allowed to wear her first choice of tiara because of concerns that it could have contained emeralds that came from Russia.

A royal insider told The Sun that the Queen then stepped in and told Harry that "She gets what tiara she's given by me."

The source said, "Meghan had her heart set on this tiara with emeralds and Prince Harry hit the roof when they were told it was impossible for her to wear it."

It took a "heated exchange" between Harry and royal staff before the Queen stepped in and ruled that her word was final.

Some fans are wondering whether the tiara in question was the same emerald-clad one that Princess Eugenie wore at her wedding that was months after Meghan's.

"The message from the Queen was very much that Meghan needed to think about how she speaks to staff members and be careful to follow family protocols," the source said.

Because Meghan was "used to working in a Hollywood environment" she can be quite difficult to deal with, the source added.

So was the Queen saving the tiara for Eugenie?
