Legendary record executive Clive Davis has 'come out' as bisexual in his new memoir.

The music mogul, who launched the careers of stars including Whitney Houston and Janis Joplin, opens up about his sexual orientation in his latest book The Soundtrack of My Life.

Davis, who has married and divorced twice, writes candidly about his first same-sex encounter with a man he met at the famous New York City club Studio 54 some 30 years ago.

He recalls, "On this night, after imbibing enough alcohol, I was open to responding to his sexual overtures... Was I nervous? Absolutely. Did the heavens open up? No. But it was satisfying."

The 80-year-old music veteran also reveals he was in a "monogamous relationship" with an unnamed male doctor from 1990 to 2004, and he has been dating another man for the past several years.

He writes, "Bisexuality is misunderstood; the adage is that you're either straight or gay or lying, but that's not my experience. To call me anything other than bisexual would be inaccurate."

Davis has also discussed his bisexuality in an interview on talk show Katie, which is due to air on Tuesday - the same day his autobiography is released.

He tells host Katie Couric, "I'm still attracted to women... You don't have to be only one thing or another (straight or gay). For me, it's the person."
