Who could forget about Prince Harry and Meghan Markle's unauthorized bombshell biography "Finding Freedom?" 

The famous book that took the world by storm last summer is reportedly getting a major update to include the biggest heartbreak of Queen Elizabeth II. 

Authors Omid Scobie and Carolyn Durand will release the updated book next month that's going to include an updated epilogue that would detail the past, including the last turbulent months of the life of Prince Harry and Meghan Markle. 

Among the topics that will be added to the book is reportedly the Duke and Duchess of Sussex's reaction to the death of Prince Philip. 

The Duke of Edinburgh died on Apr. 9 at Windsor Castle, and per his death certificate, the cause of death is attributed to old age.

Prince Harry traveled across the pond alone in April and self-isolated for five days at Frogmore Cottage before attending his grandfather's funeral service. 

During that time, the Duchess of Sussex was heavily pregnant with their second child and was advised by her doctor not to undertake a long flight and remain in California with their son, Archie Harrison. 

However, Meghan paid tribute to Prince Philip by placing a wreath at St George's Chapel, presenting a note handwritten by her. 

Prince Harry said that his grandfather "was authentically himself, with a seriously sharp wit, before the funeral in a tribute with his deeply personal statement.
