“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,” Kelly wrote in a blog on her WhoSay page on Tuesday. “Growing up is awesome because you learn you don’t have to cower to anyone — even Clive Davis.”

According to Clarkson, Davis allegedly wrote in his book (AccessHollywood.com has not seen a copy of the memoir) that she cried hysterically in the record mogul’s office after she said he “demanded” that she put “Since U Been Gone” on her LP.

“Not true at all. His stories and songs are mixed up,” Clarkson wrote.

The singer said she actually broke down about a song which she had a deep connection to.

“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,’” she wrote. “I cried because he hated it and told me verbatim that I was a ‘sh***y 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 added.
