Princess Diana poured her heart and innermost thoughts into nearly 30 secret private diaries and a bombshell new report claims that they were given to a friend for safe keeping.

The late princess, who was killed in a tragic car accident in 1997, was a prolific writer, detailing every emotion and incident that occurred in her life, including her unhappy relationship with her husband and finding new love with Dr. Hasnat Khan.

“It is dynamite stuff,” her friend Simone Simmons told The Daily Star about the numerous books she filled.

“Diana wrote everything that happened to her. How she was feeling about things and people – like Charles, Camille and everyone else in her life, plus additives in food.

“It shows her acute intelligence and concern.”

Simmons revealed that Diana favored a diary with a padlock.

“It was a proper school girl diary with a key to keep away prying eyes.
