THE Queen warned Prince Harry over Meghan Markle’s behaviour and attitude before their wedding following a row over the bride’s tiara.
The extraordinary intervention from the monarch came after tense negotiations over what Meghan could wear.
She initially wanted a tiara that featured emeralds, according to royal sources. But the future Duke and Duchess of Sussex were unhappy when told her first choice was impossible, as no one knew exactly where it came from.
A new book by reporter Robert Jobson reveals Harry told staff before the wedding: “What Meghan wants, Meghan gets.”
But Meghan, 37, eventually wore a diamond and platinum headpiece which was chosen by the Queen.
A well-placed royal insider 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.
“The provenance of the tiara could not be established. There were concerns it could have come from Russia originally.
“There was a very heated exchange that prompted the Queen to speak to Harry. She said, ‘Meghan cannot have whatever she wants. She gets what tiara she’s given by me’.
“The Queen also questioned why Meghan needed a veil for the wedding, given it was to be her second marriage.
“The message from the Queen was very much Meghan needed to think about how she speaks to staff members and be careful to follow family protocols.”
In an interview, Meghan said she chose the tiara she did wear after visiting Buckingham Palace with Harry, 34, to see the Queen and view the “options”.
It has also emerged Meghan and Kate, the Duchess of Cambridge, 36, have clashed over the treatment of staff.
The royal insider added: “Meghan can be difficult.
“She has very high standards and is used to working in a Hollywood environment.

“However, there’s a different degree of respect in the royal household and Kate has always been very careful about how she has acted around staff.”
A spokesman for Meghan and Harry declined to comment.
Meanwhile, Robert Jobson’s book, Charles at 70, said the Queen and Meg have bonded over a love of dogs.
