Katie Price has launched a fierce attack on her ex-boyfriend Kris Boyson, accusing him of being "un loyal" and arranging paparazzi pictures without her knowledge.

The 42-year-old dated the personal trainer for around 18 months, even getting engaged and making plans to have a child before calling it quits last November.

After a publicly-acrimonious split, Price has since found love with car salesman Carl Woods, while Boyson is with new girlfriend Bianca Gascoigne.

Responding to a follower who was praising Boyson on her Instagram, Price launched into a rant against her ex, also attacking Gascoigne for being "fame hungry" and a "z lister".

"I was completely fooled by Kris who set up Pap pictures behind my back, bought me a ring he took back, wouldn't give back my gym equipment he uses to run his business with, wouldn't give back Harvey's log cabin..." she alleged.

"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 un loyal, introduced me to the main who totally wrecked my house and fly tipped and stole off me and behind my back trying to crack a deal making money behind my back!

"Made out he had money but hasn't a pot to piss in I paid for things! He acted as if he was into the kids and total wasn't, then went for a z lister who had been with my exes who is also fame hungry they deserve each other and guess what he us the past and can stay there!

"I have my ultimate future my today tomorrow forever and that's my Carl. so go and digest that my darling."

Price has previously warned all of her exes that she will not hold back about them in her upcoming seventh autobiography.
