One of the top professional singers today once experienced a personal demon that greatly affected her personal life and career.

According to a biographer, Adele once had a drinking problem that affected the concert performances of the 24-year-old British singer. Biographer Marc Shapiro, who penned the unofficial book, Adele: The Biography, that chronicles the singer/songwriter’s childhood in North London as the daughter of a single mother, said the drinking problem was bad enough that the singer would forget the lines she was supposed to be singing during concerts.

The much-awaited book is set to be released worldwide on July 17. Shapiro said the singer’s father is an alcoholic. He also portrays Adele’s life as a rags to riches story with the star starting with nothing before becoming a famous singer.

The biographer also said that much like her songs, Adele has experienced many failed love affairs. To all the Adele fans around the globe, do not miss the chance to learn more about your idol by buying the book when it hits shelves soon.
