The pregnant reality star has revealed further details about Danny's appearance in the fifth instalment of her life story, following her recent promise to 'reveal everything' during a heated Twitter row with the celeb couple.
Speaking to HuffPost UK on the release of her latest novel, 'He's The One', Katie branded the rugby star a "nasty piece of work" who deserves "every bit of bad press".
"He is in [the autobiography] and he deserves to be in there. What a little sh*t he is, and everyone will know," she said.
"Every bit of bad press that guy deserves. I'm not going to go into detail but like I say, he is a nasty piece of work that man."
Katie is rumoured to have enjoyed a brief romance with Danny last year, which has been making headlines again thanks to her feud with the sportsman's current girlfriend Kelly Brook.
The row started after Katie branded her a 'heifer' in her column in The Sun, and the artist formerly known as Jordan later warned Kelly that Danny would "never be faithful", tweeting: "Ask danny about his emails & texes sent to me behind your back which ill show you kieran agrees he will never be faithful (sic)."
Further teasing her new autobiography - out in October - Katie promised fans it would be a "disturbing" and "emotional" read.
She told us: "I seem to do it every two-and-a-half-years like a diary and the last time I thought there's no way anything can beat it. But the last one finished from when I married Alex (Reid) so there's lots to go in there," she said.
"It's a disturbing read, emotional - obviously it's got good bits in but it shows a different side."
Katie is currently expecting her fourth child - her first with third husband Kieran Hayler, who she wed earlier this year after a whirlwind romance - and also admitted that the pregnancy had "not been easy".
She said: "I haven't really spoken about the pregnancy, but it hasn't been an easy one. It's been hard."
Adding that she has still been working since falling pregnant, she said: "I obviously didn't know I was going to be pregnant, so you still have to carry on and work. All pregnancies are knackering, but it's my fourth one, so I'm pretty used to it."
