The 24-year-old Brit reportedly admits in the book that she struggled with alcohol abuse after failing to deal with her early success.
She is said to have recounted an incident where she was in such a stupor on her first tour that she fell off her stool mid-concert and forgot the words to some of her own songs.
The unofficial Adele: The Biography was penned by biographer Marc Shapiro and chronicles the singer-songwriter’s humble north London beginnings as the daughter of a single mother.
He then documents the ups and downs of her love life, musical success and the vocal cord haemorrhage which led to her cancelling last year’s US tour and needing surgery.
In an interview with In Touch Weekly, Shapiro said: ‘It’s a classic rags to riches.’
The writer is alleged to have revealed that Adele’s father was an alcoholic and that despite having a loving mother Adele has found herself searching for affection to make up for her absent dad.
On discussing her reported alcohol abuse, he said: ‘Adele would drink more than normal to salve the heartbreak.
‘Midway through her first tour, she allegedly had a drinking problem.’
Shapiro’s unofficial Adele biography is scheduled to hit shelves on July 17th.
