The personal trainer has hit out at his former girlfriend after she accused him of "using her for fame" before taking a swipe at his new partner, Bianca Gascoigne, and alleged the 'Loose Women' star slept with three other men during their relationship.

Kris insisted he "didn't want to have to do this" but insisted he had no choice as Katie is "constantly trolling" him in a lengthy post on his Instagram Story.

He said: "I've come on here today just to set the record straight, I'll be careful with what I say as I'm not out here to destroy anyone's career, which I could quite easily do but I'm not that sort of person.

"I am not fame-hungry and I'm not trying to make money, or I could have sold it all to the press.

"I didn't want to do this, I've never done it before - I've always been very amicable through everything… But how much more can I take?

"I am ignoring most of your comments as they're a waste of everyone's time, I just want to touch on a few things you said."

Believed to be referring to the 42-year-old star's stint in rehab, the 31-year-old hunk said he had "supported her on things that a lot of people said he shouldn't have" and claimed Katie had admitted to cheating on him but realised losing him was "the biggest mistake of her life."

And on taking back a ring he'd given her, he said: "Why am I going to let you keep a ring of that value after I find out you're sleeping with three other people?"

And Kris even hit out at Katie's parenting, claiming he would stay at home "all weekend" with her five kids while she was out with Charles Drury, who she allegedly had an affair with in response to her accusing him of never being there for Harvey, 18, Junior, 15, Princess, 13, seven-year-old Jett, and six-year-old Bunny.

He fumed: "Their dads will vouch for this as they've acknowledged it before; I treated every one of those kids as though they were my own.

"Let's not even talk about Harv; I was there 24/7 for that kid and gave him every bit of support and helped him out in every way I could.

"I'm not here to ruin anyone or open a can of worms but remember that whole weekend that you went to that hotel with that Drury fella? Who was looking after the kids?

"Who was building them new bedrooms and working my ass off between work to make your kids comfortable in my house?

"I wouldn't want to start touching on the endless nights that staying out was more important than coming home to the kids."

Kris went on to hit out at his former partner for branding Bianca a "z-lister" and told her to leave them alone and focus on her own new romance with Carl Woods.

He said: "I don't know why you're bringing Bianca into this, I don't know what she's done to you - she's done nothing wrong.

"You're supposedly happy so move on quietly like I have done, and I wish you two guys all the best."

Kris decided to speak out following Katie making a series of allegations about him in response to a fan on Instagram, including that he had used her for money, staged photos of them, stole her gym equipment and "totally wasn't" interested in her kids.

She ranted in the now-deleted post: "He never stuck up for me, always wanted to be in my tv show wanted to do photo shoots with me yet I refuse, he was very unloyal."

She then branded Bianca a “fame-hungry z-lister”.
