Music industry legend Clive Davis reveals he's bisexual in new memoir Kelly Clarkson says she feels "bullied" by "false claims" printed in Clive Owen's tell-all memoir. RECORD executive Clive Davis holds nothing back in his autobiography, opening up about his bisexuality, early childhood and some "false" claims about Kelly Clarkson. In his new memoir the 80-year-old, who is twice divorced, reveals that he had sex with a man in the 1970s. "On this night, after imbibing enough alcohol, I was open to responding to his sexual overtures," he writes in The Soundtrack of My Life, released today. The record industry icon says in his 500-page tell-all that he hadn't been repressed or confused during his marriages and that sex with a man "provided welcome relief." He also writes that he started dating a man from 1990 to 2004, which he says was a "tough adjustment" for his son Mitchell. He says after "one trying year," he and his son worked things out. Davis is the father of three children. Davis also claims that American Idol winner Kelly Clarkson - who he signed to RCA Records - burst into "hysterical sobbing" after he forced her to include her single Since U Been Gone on her 2004 Breakaway album. Clarkson says the story is false. Kelly took to her blog to say that she has been "bullied" by Davis' false claims: "So I just heard Clive Davis is releasing a memoir and spreading false information about me and my music. I refuse to be bullied and I just have to clear up his memory lapses and misinformation for myself and for my fans. It feels like a violation..." the pop star tweeted to her 2.9 million followers. "He says I burst into "hysterical sobbing" in his office when he demanded Since You Been Gone be on my album. Not true at all. His stories and songs are mixed up. I did want more guitars added to the original demo and Clive did not. Max, Luke and I still fought for the bigger sound and we prevailed and I couldn't be more proud of the life of that song. I resent him dampening that song in any way," the singer wrote. Davis is the chief creative officer of Sony Music Entertainment and has discovered and signed dozens of artists including Alicia Keys, Jennifer Hudson, Bruce Springsteen and, most famously, Whitney Houston. He writes that he's been in a "strong monogamous relationship" with a man for the last seven years.
