Kris Boyson vows to 'stick by' Katie Price's son Harvey amid reports that their relationship is 'on the rocks'

Katie Price’s boyfriend Kris Boyson has vowed to “stick by” her son Harvey, after it was reported that his relationship with the former glamour model is ‘on the rocks.’

The personal trainer promised to support the 16-year-old as he hit back at a troll who had criticised Price for bringing “another so called ‘dad’” into Harvey’s life.

Commenting on an Instagram photo which showed Boyson cuddling Harvey on the sofa, the troll wrote: “Poor Harvey another so called ‘dad’ who’s come into his life you’re the biggest mug going if you thing [sic] it’s going to last.”

“@officialkatieprice you need to learn to stay single and put your kids first for a change,” they added.

Boyson proved his dedication to Price’s children as he fired back at the Instagram user, describing them as “insecure.”

“Another insecure woman getting her insecurity fix by messaging me about someone else’s life,” he wrote.

“If a mug is somebody who has stuck by a disabled child then you must be the Devil. Now p*** off.”

Earlier this week, it was reported that Boyson and Price had been ‘rowing’ constantly while on holiday to Spain,

“Katie and Kris have been rowing the entire holiday over pretty much everything. Katie has been working so hard on the reality show, she’s been snapping and grumpy with Kris, and in turn he’s been playing up to the cameras,” a source told The Sun.

“Being trapped on a working holiday together in the campervan hasn’t gone well and the relationship is on the rocks with them bickering the whole time.”

Standard Online has contacted Price’s representatives for comment.

The couple are thought to be filming scenes for Price’s reality series My Crazy Life as they accompany her terminally ill mother Amy on a ‘final’ holiday.
