American Idol winner Kelly Clarkson has hit out at record executive Clive Davis for statements he made about her in his memoirs 'The Soundtrack of My Life'.

The 80-year-old Sony music executive is best known for launching the career of Whitney Houston, but has also worked with everyone from Aretha Franklin to Bob Dylan to Alicia Keys over the course of his career and mentored Clarkson following her American Idol victory over ten years ago.

In the book, David claims considerable "creative differences" between him and Clarkson and that Clarkson would fall into "hysterical sobbing" during discussions about the direction of her music - a claim which Clarkson was quick to dispute on Twitter.

"He says I burst into "hysterical sobbing" in his office when he demanded 'Since You Been Gone' be on my album. Not true at all", Clarkson wrote. "His stories and songs are mixed up. I resent him dampening that song in any way."

Clarkson further disputed claims made by Davis in which he said that the singer's third album didn't perform well because she had too much creative control on it by stating that the music mogul sabotaged the album's potential by publically belittling it at a music convention.

Davis responded to Clarkson in an online statement, saying: "I am very truly sorry that [Clarkson] has decided to take issue with what I know to be an accurate depiction of our time together."

Elsewhere in his memoirs Davis goes on to reveal that he's bisexual, Bob Dylan accused him of censorship and that he pleaded with Whitney Houston to end her drug habit towards the end of her life. Just a bit of light reading, then..
