Cheryl Cole has admitted that she told Simon Cowell she ''hated'' him when she was axed from the US version of The X Factor.

In her autobiography Cheryl: My Story, which is being serialised by The Sun newspaper, she wrote: ''I was furious with Simon for letting it happen like this. I believed we had a good friendship and couldn't understand why he hadn't been straight with me.

''I wrote the longest text ever. 'F*** you, f*** Britain's Got Talent, f*** the orange and purple outfit. F**k big hair. F*** the UK X Factor. F*** you all'.

'''I hate you. I understand you're a businessman, and what I've learned from this is business means more to you than friendship. I'm sad it's got like this and I wish you the best of luck, but count me out.' Simon texted back, 'Can I talk to you?' I ignored him.''

Cheryl, who declined an offer to return to the UK version of the show, finally agreed to speak to Simon months later and he admitted firing her from the US programme was the ''worst mistake'' he ever made.

She added: '[He said], 'I wasn't in the right frame of mind in LA because of all the expectation on the American show... Taking you off it was the worst mistake I ever made and if I could have my time back, I wouldn't do it again. I'm sorry''.

Cheryl: My Story is released on October 11th.
