UPDATE: Clive Davis called BS on Clarkson calling BS. The music exec said he had "every fact checked" in his book and what he wrote was an "accurate depiction of our time [working] together."

Well, that was fast. The love/support fest for legendary music exec Clive Davis—who just revealed his bisexuality—has already come to a screeching halt. After getting wind of what he wrote about her in his just-published memoir The Soundtrack of My Life, Kelly Clarkson is calling bullsh-t on Davis' version of their professional work history. 

"I just heard Clive Davis is releasing a memoir and spreading false information about me and my music," Clarkson wrote in an online post. "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."

Clarkson denied Davis' account that she dissolved into "hysterical sobbing" after he demanded she put "Since U Been Gone" on her album, implying she didn't like the song at all. According to the Idol queen, the disagreement was not over the inclusion of the song but its rock-oriented sound: "I did want more guitars added to the original demo and Clive did not. Eventually I prevailed and I could not be more proud of that song." 

Clarkson wrote the crying incident was over another fight entirely: "I cried because he hated [my song 'Because of You'] and told me verbatim that I was a 'sh-tty writer who should be grateful for the gifts that he bestows upon me.' He continued on about how the song didn't rhyme and how I should just shut up and sing." Ouch. And you thought your boss was a jerk!
