Actress Demi Moore has opened up about losing a pregnancy with her ex Ashton Kutcher and reveals that she was raped when she was 15 years old.

In an interview with the New York Times ahead of the release of her biography “Inside Out”, Moore says she believes the trauma of losing the chold sparked a long battle with her body image, which saw her obsess over her weight and abuse alcohol and cocaine.

The actress, 56, told how she was still drinking alcohol while six months pregnant with Ashton’s baby.

When she lost the girl, who she had intended to name Chaplin Ray, Demi blamed herself for the miscarriage.

In the interview, Demi revealed she suffered a seizure after smoking synthetic cannabis and inhaling nitrous oxide while partying in 2012.

The book, according to the New York Times, is a candid personal narrative, in which Moore fills in not only the details surrounding the most visible parts of her history — her Hollywood career and her much scrutinized marriages to the actors Bruce Willis and Ashton Kutcher — but the portions of her life that she once fought to protect, including the confusing and all-too-abrupt childhood that preceded her choppy show-business ascent, and a more recent relapse into substance abuse that nearly tore apart her family.

The book will be released on 24 September.
