The author of Princess Diana’s book, “Diana In Private,” recently threw shade at Andrew Morton, the author of “Diana” and “Diana: Her True Story – In Her Own Words.”

According to Express, Campbell found out that Morton’s books are being adapted into a stage play. “Yet again, Morton follows in my wake,” she said. Campbell and Morton’s books both give some insight on Princess Diana’s life that was reportedly filled with sadness.

Morton’s play will center on “The Diana Tapes” by James Clements. Campbell is hoping that her version of the story will also be shown in the West End. “I was left with some deep conversations that made it into the book, which I have used for the play. It’s hard-hitting because the rawness of her words will show she was not so much a sacrificial lamb as first depicted,” Campbell said.

Both of Campbell and Morton’s plays will be staged around the same time as Prince Harry and Meghan Markle’s wedding. Morton is currently busy writing a memoir about the former “Suits” actress.

Last month, news about Morton’s stage play first came to light after Sky News reported about it. The synopsis for “The Diana Tapes” reveals that the stage play will revolve around Princess Diana’s shocking confessions about her personal life, as well as her marriage to Prince Charles.

“Based on the real transcripts from the Princess’s tapes, the show moves between Morton’s office, the sitting room where the Princess recorded the cassettes, and the dingy West London café where one of her best friends surreptitiously handed them over,” the synopsis read.

“The Diana Tapes” is directed by Wednesday Sue Derrico. The New York-based production will premiere at HERE on May 24. The shows will wrap up on June 10, and the cast and crew will move to London for a series of shows.
