Katie’s memoir, titled This Is Me, sees the Page 3 legend slamming the men from her past in it.

KATIE Price’s furious ex fiancé said he’s ‘calling lawyers on her’ and threatened to punch her new boyfriend JJ Slater amid a ‘cheating row.’

Katie Price, 46, began dating Kris in May 2018 and, by July, there were already wedding rumours circulating.

By September, they had split – but later rekindled their romance.

The couple continued to be on-and-off until they eventually broke up for good in 2019.

Recently, Kris slammed Katie as a “complete liar” in a row over cheating, after she made a savage swipe at her ex-boyfriend Kris in her new book, titled This Is Me.

Now, Kris can be seen in a new video shared on social media making his thoughts clear.

Pacing back and forth while holding the camera, he says: “Everyone that knows me knows I’ve been pretty humble, amicable and have kept my mouth shut about a lot of things that have happened in the past.

“Because I don’t like drama coming to people’s doors and two, I’d rather just take the drama and take the s*** and I’m strong enough to deal with it.

“However, being brought back into it and having s*** written about me isn’t going to happen and isn’t going to go away lightly.

“Especially about someone that publicly told the world that I’m the only guy that didn’t cheat on them.”

Kris continued: “And saying ‘I’m the one that got away,’ and ‘oh my god he treated me so well’ as the family all said as well, who are great by the way.

“So anyway all I’m saying on this matter is if you want to start talking s*** about stuff that you’ve done and blaming it on me, it aint going to end well for you.”

Kris went on: “Personally, I’d keep your mouth shut because s*** is going to done otherwise, trust me.

“I aint really going to let it bother me. My agent is currently dealing with it and if it means a law suit has to come into place then so be it, but you won’t like that and it’ll be a ball ache for you.

“I’m sitting pretty right now, if you want to do it let’s do it.”

Kris was at the O2 Arena at the time of filming the video, and he had a few words for Katie’s current boyfriend, MAFS star JJ Slater.

He went on: “Whilst we’re talking about boxing, if you really want to carry on running your mouth then tell your fella to lace his gloves up like we’ve been asked to before and he keeps bottling it, and let’s jump in the ring and settle it.

“But yeah, stop running your mouth because s*** is going to come on your doorstep, and the only difference between me and you is that I’ve got proof. Years of proof.”

Katie’s memoir, titled This Is Me, sees Page 3 legend slamming the men from her past in it.

In one chapter, she wrote: “Then I met Leo, and he was very good looking, but he ended up annoying me in every possible way so that was over pretty quick.

“He always made noises in bed, or when he ate, and he would wait for me to entertain him and in the end I just got annoyed.

“Then I was with Kris Boyson but he cheated on me and coming off the back of Kieran, I was devastated, so that damaged me too.”

Personal trainer Kris, 34, has denied these claims and said her version of events are not true.
