The 80-year-old record producer, who helped clients like Whitney Houston and Alicia Keys achieve mega success, admits to have been in relationships with two men for the past 20 years.

During an interview with ABC's Nightline, Davis says:

    "For over 50 years I never had sex with a male. I wasn't repressed. I had very good sexual relationships with women."

Davis, who has been divorced twice, adds, "The subject of bisexuality really needs much more discussion. It's a status that does exist."
