Among many fascinating revelations in the new memoir of Clive Davis, titled ‘The Soundtrack Of My Life’, comes one pretty big surprise – he’s bisexual.

Davis revealed that his first sexual activity with a man came during the era of Studio 54 – a renowned nightclub in New York open from 1977 until 1981. "On this night, after imbibing enough alcohol, I was open to responding to his sexual overtures," writes Davis in the book, according to NBC. Being with a man, he writes, provided "welcome relief." Davis ultimately separated from his second wife, after a period of "soul searching and self-analysis," in 1985. From then he revealed that he went on to have simultaneous relationships with two women and a man.

Things went further in 1990 when he entered into a "monogamous relationship" with a male doctor, the pair staying together for 14 years until 2004 when they split. Davis has also apparently been in another relationship with a man ever since. The book is an overdue update on Davis’ first book Clive: Inside The Record Business, released in 1975. The sequel sees Davis, record producer and music industry executive whose won five Grammys, recount tales with stars including Bob Dylan, Bruce Springsteeen, Whitney Houston, Michael Jackson and Kelly Clarkson, among others.
