It's becoming a classic he said, she said and then he said she's got it all wrong.
On Tuesday, Davis counter-punched and denied he bent the truth in describing the sessions for Clarkson's debut album and their subsequent battles over her career.
"As anyone who has read 'The Soundtrack of My Life' knows, I think Kelly Clarkson is a tremendous vocal talent and performer," Davis tweeted. "In the book, I provide an in-depth look at our years together during which we shared major multi-platinum success, as well as a few creative differences. I am truly very sorry that she has decided to take issue with what I know to be an accurate depiction of our time together."
Davis continued that before the book was published he had every fact checked with five independent individuals who were present on a daily basis throughout the incidents described. "The chapter as it is written was thoroughly verified by each and every one of them," he wrote. "I stand by the chapter as written in my book. At the same time I wish, and will always wish, Kelly's talent and her career to soar to ever new heights."
Clarkson was signed by Davis and "American Idol" boss Simon Fuller to RCA Records after winning the first season of the show. In his book, Davis wrote that the singer burst into "hysterical sobbing" after he forced her to include her massive single "Since U Been Gone" on her 2004 Breakaway album. Clarkson said that story was not the way she remembered things at all, though.
"His stories and songs are mixed up. I did want more guitars added to the original demo and Clive did not..." Clarkson wrote. "But, yes, I did cry in his office once. I cried after I played him a song I had written about my life called 'Because Of You.' I cried because he hated it and told me verbatim that I was a 'sh--ty 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. This was devastating coming from a man who I, as a young girl, considered a musical hero and was so honored to work with. But I continued to fight for the song and the label relented. And it became a worldwide hit. He didn't include that in the book."
She explained that she penned her response letter after Davis' version of their story made her feel "violated" and because, "Growing up is awesome because you learn you don't have to cower to anyone — even Clive Davis."
Though there are other discrepancies Clarkson pointed out in the book — including a scene in which the singer said Davis "completely sabotaged" her My December album by belittling it in front of RCA staffers — she concluded that she was, "grateful for Clive teaching me to know the difference" between loving her job, her music, her fans, label and professional relationships.
