Meghan Markle and Prince Harry will reportedly work with 'friendly' journalists to pen their biography.
The couple have reportedly been interviewed as part of their ground-breaking book which is said to be titled 'Thoroughly Modern Royals: The Real World Of Harry And Meghan', sources said.
The book is reportedly 320 pages and is aimed at portraying a positive image of the Duke and Duchess of Sussex and their decision to step down as senior royals.
It comes days after Harry and Meghan announced they would no longer engage with certain British newspapers as they continue their new life in America.
It is reported their book will be written by royal reporter Omid Scobie, who was one of the few journalists given details of Meghan, Harry and Archie's video call to the Queen on her 94th birthday.
Second author, American journalist Carolyn Durand, is also close to the couple and has been writing about the royals for 15 years.
The Royal family are said to be worried about what Meghan and Harry may divulge in their biography.
After announcing they would no longer engage with some tabloid British newspapers, Meghan hit headlines once again as she sued the Mail of Sunday.
She has taken the publisher of the Mail on Sunday and MailOnline to court over a "private and confidential" letter to her estranged father, Thomas Markle.
The letter at the centre of the Duchess of Sussex's legal battle with a British newspaper detailed her intimate "thoughts and feelings" about her father's health and their relationship, it is claimed.
The duchess is bringing legal action against Associated Newspapers Ltd, publisher of the Mail on Sunday and MailOnline, over an article which reproduced parts of a handwritten letter she sent to her father, Mr Markle.
In court documents outlining Meghan's claim against the publisher, her solicitors say that the letter was "obviously private correspondence" and she did not expect the contents to be made public.
Sections of the letter, which was sent to Mr Markle, 75, in August 2018, were published in February in the Mail on Sunday and on MailOnline.
The headline on the article read: "Revealed: The letter showing the true tragedy of Meghan's rift with a father she says has 'broken her heart into a million pieces'."What vice could you never give up?
