Hell hath no fury like a Kelly Clarkson scorned. Clive Davis learned this the hard way when the 'Stronger' singer wrote a long open letter yesterday refuting the claims of the producer and record exec in his memoir 'The Soundtrack of My Life.' But Davis is not letting Kelly get the last word. He wrote,

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.

Wow. This has turned into a classic case of he said, she said. We will likely never get the real truth on the riff between Clarkson and Davis, but it seems plausible that Davis is the bully Kelly is alleging. Perhaps the five independent individuals the facts were verified with have been also been intimidated by Clive in the past and were afraid to refute the claims he made. The record exec's statement also seems to be backpedaling a bit, mostly focusing on the great success they had together as opposed to focusing on the issues Kelly brought up in her open letter.

Or maybe, the 'Since U Been Gone' songstress is just a major drama queen. We may never know!
