The death of MARILYN MONROE drove fragile beauty NATALIE WOOD to seek psychiatric help – terrified that she’d meet the same tragic fate as the ultimate blonde bombshell!

That’s yet another disclosure from Natalie’s secret diary – a chilling 118-page document kept hidden under lock and key until The National ENQUIRER obtained it exclusively.

“I had known her [Marilyn] and seen her days before her death,” Natalie wrote. “Her beauty, charming wit and joy of life seemed paradoxical to the intense loneliness which she faced in her life.”

Of Marilyn’s passing, the “West Side Story” star penned: “Her death, the waste of her beauty, talent and worth as a human being had an enormous effect on me. One of the effects was that I again mobilized my resources to seek help in analysis.”

Natalie, who died in 1981 under puzzling circumstances after a wild night with husband Robert Wagner and “Brainstorm” co-star Christopher Walken, also confided to her mother that she was desperately worried she’d “end up like Marilyn.”

Natalie’s sister Lana Wood shared the diary in hopes it could help detectives with their probe into her death.

The journal also reveals Natalie found herself in a love triangle with Liz Taylor when she began dating Liz’s ex-husband Nicky Hilton.

She wrote: “I met Nick a few years after his divorce from Elizabeth Taylor [in 1951] on a junket to Mexico City. Nick had wanted to meet me … I was terrified of flying, and annoyed at the studio for making me go. But it turned out I had a fabulous time.

“For a while, Nick and I thought we loved each other. But we both had fiery tempers, and we clashed often over insignificant things.”

Natalie’s heartbreaking diary also reveals she suffered intense loneliness.

She confessed: “When I think of my early years, it seems as if I spent most of that time auditioning. I was terribly insulated from the world outside the studio. So I didn’t know how to react to situations that seemed conventional to other children.

“The most important thing in my early years was to win the approval of others. It was only later that I learned that it was equally vital for me to develop self-esteem.”
