A new memoir called 'Fairy Tale Interrupted' claims that the late John F. Kennedy Jr. once asked Madonna to pose as his mother, Jacqueline Kennedy Onassis, for the cover of his magazine, George.

JFK Jr.'s assistant and confidante, RoseMarie Terenzio, has written a book about her time with the magazine publisher, who tragically died in a plane crash along with his wife, Carolyn Bessette-Kennedy, on July 16, 1999. As the New York Post reports, the title includes a recounting of the request, which Madge turned down, saying she would "never do [Jackie O] justice."

"We'll have her in a pillbox hat, sitting on a stack of books,” JFK Jr. suggested for his September 1996 'Women in Politics' issue. According to the memoir, a letter was drafted to the Material Girl, but Madonna promptly faxed a handwritten response declining the offer.

"My eyebrows aren’t thick enough, for one," Madonna said in the note, adding, "When you want me to portray Eva Braun or Pamela Harriman, I might say yes!"

Ultimately, Drew Barrymore was selected to grace the cover of the magazine, ironically portraying Marilyn Monroe in her iconic white halter dress singing 'Happy Birthday, Mr. President.'

Terenzio's book is set to hit shelves on Jan. 24.
