Following its publication, Katie took to Twitter to slam the journalist who wrote the story, and insisted the claims “could not be further from the truth”.
She wrote: “Such a pricey shocker well sorry to shatter your illusions but you couldn’t be further from the truth! I love him and not splitting up #lies.”
She then posted screengrabs of an email the reporter had sent her spokesperson, adding: “From the horses mouth me and kieran are 100% together not splitting up we are very happy and very much in love leave our relationship alone.”
Katie also insisted a “lawyer letter” was being prepared as she typed.
She later posted a series of pictures of her and Kieran on Instagram, as they enjoyed a night out with friends:
The star is currently on a break from ‘Loose Women’, revealing last month she was taking some time off to focus on her marriage.
Katie claimed the publication of her latest book, which details Kieran’s affair with her best friend Jane Poultney, had “opened old wounds”.
Speaking on the show, she said: “It’s been awful. I thought I’d dealt with it. I was numb when it all happened. I’m quite good at putting up a defence, but it’s been torture.
“I haven’t got any tears to cry. My heart is shattered, it’s broken. We’ve come two and a half years and Kieran is having to re-live it.”
Katie, who was previously married to Peter Andre and Alex Reid, has since announced she will return to the ITV daytime show in December.
