The book, which is being serialised by the Sun, sees Katie, 35, slam her ex Pete, and knocks his claims that it was her who destroyed their relationship after their split in 2009.
“I was still reeling from the devastating loss of our baby (in 2009). I knew our marriage had been on the rocks for a while. But I never thought he’d leave me. I was heartbroken. I thought I’d found ‘the One’ — the man who completed me, the man I wanted to spend the rest of my life with.
‘The way he behaved after we split proved to me I could never trust him again. Within weeks Pete was promoting his new album. I’ve always wondered how he’d have promoted it if we hadn’t split up.”’
The mother of four explains she felt Pete tarnished her name to further his own career.
“(He was) held up as some kind of saint, the perfect father, and a victim” — while “I was a bitch and a bad mother”.
She says: “He’s never, to my knowledge, said anything to the press to contradict this impression. I was back to being called Jordan and blamed for the break-up of our marriage. There seemed no sympathy for me at all.”
Katie and Peter split in 2009 after three and a half years of marriage.
Katie goes on to speak about her more recent romance with 25 year-old Danny Cipriani, and how she sneaked into his flat in to catch him with another woman.
"My heart was pounding and the adrenalin was pumping through me as we went quietly up to Danny’s bedroom. The door stood slightly ajar. We all walked in. Then we froze as we looked at the bed.
My gut instinct had been spot on. Danny, who was supposed to be my boyfriend, was having sex with another woman.
The effect on the couple in the bed was instantaneous. They stopped what they were doing and grabbed the duvet to cover themselves.”
Katie is now married to 25 year-old model Kieran Hayler and the couple recently celebrated the birth of their new-born son Jett Riviera.
