Prince Harry and Meghan Markle may not care about an explosive new book about them as they "just play the victim", a royal expert has said.
The couple has become the latest famous face to become the subject of a biography by renowned and feared author Tom Bower.
Among the allegations in Mr Bower's book are that Meghan threw a cup of tea in the air during a Royal tour, while the Queen was said to be pleased the duchess couldn't attend Prince Philip's funeral.
The book also claims that Harry and Meghan wanted to appear with the Queen on Buckingham Palace's balcony during the Platinum Jubilee celebrations last month.
Mr Bower has admitted that those who helped with his research of the book were people who were "less than fond" of the couple - with Harry and Meghan having no input whatsoever into the biography.
But despite the book containing many stinging criticisms of the couple, royal expert and author Duncan Larcombe says the Sussexes may not even be phased by it.
He told OK! magazine : "I’m beginning to think they are almost impervious to criticism. Any criticism and they just play the victim so it’s like, ‘Oh poor us – these horrible people’.”

Later this year, Harry is set to release his own memoir, which he has promised will be an "accurate and wholly truthful" account of his life so far.
And according to Duncan, the prince could use this book to set the record straight and counter any claims against him and Meghan.
He added: "I know that he has a real desire to tell his own story in his words.
"I would be very surprised if he didn’t try to fight back against some of that criticism and if there’s no truth in these claims then I guess Harry is going to try to set the record straight.”
The comments come after reports that that Harry's eagerly anticipated memoir will be released later this year - in time for Christmas shoppers.
It is claimed that Harry's book, which the prince has described as a "truthful and wholly accurate" account of his life, is now written and has been signed off by lawyers.
It is hoped that the book will be released later this year around Thanksgiving in the US in late November in time for the Christmas market.
A publishing source told The Sun : “The manuscript has been finished and gone through all of the legal processes.
"It’s done and out of Harry’s hands. The publishing date has been pushed back once but it is on track for the end of the year.”
