Kelly Clarkson has come out swinging at Clive Davis, whom she accuses of "spreading false information about me and my music" and bullying.

Davis is currently making the media rounds in support of "The Soundtrack of My Life," a new memoir in which he reveals he is bisexual and had "loving relationships and sexual intimacy" with both men and women. Clarkson took issue with a very different passage, in which the music mogul apparently writes that she broke into "hysterical sobbing" when he demanded that smash hit "Since U Been Gone" would be included on Clarkson's album.

"Not true at all," Clarkson wrote in a WhoSay post on Tuesday. "His stories and songs are mixed up. I did want more guitars added to the original demo and Clive did not. [Producers Max Martin and Łukasz "Dr. Luke" Gottwald] 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."

UPDATE: Davis' team has responded to Clarkson's note with a statement of his own:

    As anyone who has read "The Soundtrack of My Life" knows, I think Kelly Clarkson is a tremendous vocal talent and performer. 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. Before the book was published, I had every fact checked with five independent individuals who were present on a daily basis throughout it all. The chapter as it is written was thoroughly verified by each and every one of them. 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.

The "American Idol" winner goes further, alleging that Davis berated her after she played him "Because of You." "I cried because he hated it and told me verbatim that I was a 'sh-tty writer who should be grateful for the gifts that he bestows upon me,'" Clarkson writes. "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."

Eventually, the label placed "Because of You" on the album, and it went on to be a smash hit. Clarkson goes on to say that she's since found fulfillment in all her professional relationships, thanking Davis "for teaching me to know the difference" -- presumably between ill-wishers and supportive partners.

In 2007, Clarkson took to her website (via People) to address reports that a feud had emerged between her and Davis:
