Katie Price blames Peter Andre for damaging her reputation in order to make his television show Peter Andre: My Life a success.
The mum-of-four and glamour model thinks Peter trashed her reputation and made her out to be a villain so the public would think of him as the 'victim'.
In her explosive new autobiography, Love, Lipstick and Lies, which is being serialised by The Sun newspaper, she writes, "I thought we had a secure, happy family, something which I have always wanted. But that happy family was destroyed when Pete walked out - telling me it was over in a phone call."
She added, "He would often drop hints in the magazine interviews he subsequently gave that there was a dark secret behind our divorce. There was no dark secret."
Katie also argued that Peter moved on too quickly, promoting his album within weeks of them going their separate ways.
The pair ended their three-and-a-half year marriage in May 2009, but in 2011 Peter took to TV to talk about their relationship with Piers Morgan. On the show he admitted, "Katie said the reason I left her was because I'd seen pictures of her in nightclubs flirting with other men and presumed she'd cheated on me. That is not the truth. Those pictures were not the reason I left Katie. I would never end a marriage over something small, or little things building up.
"Something big happened, which I won't reveal as I don't want my kids reading it. But when I tell them, I'll come on your show and reveal what actually happened.
"Katie knows 100 per cent the reason why I left her and I am 100 per cent sure that what happened definitely did happen."
Love, Lipstick and Lies by Katie Price is available on 24 October, 18.99, Amazon.co.uk.
