Demi Moore has revealed she was raped at 15 in her new memoirs, it has been claimed.

The actress, 56, will recount harrowing details about the sexual attack in her new book Inside out, according to The New York Times.

The book will span from her difficult childhood to her high-flying Hollywood career.

It will also give an inside look at her high-profile marriages to actors Bruce Willis and Ashton Kutcher as well as raising her three daughters.

Demi expressed penning the memoirs made her feel “very vulnerable” as she shared the intimate details about her life.

However, the American actress explained writing the book was something she wanted to do to “rediscover” herself.
