Made in Chelsea star Stephanie Pratt has accusedLove Island star andex-boyfriendJonny Mitchell of cheating just days after it was announced they had ended theirthree-month relationship.

While Jonny said in a statement earlier this week that he had "fond memories of the times they spent together," Steph has taken to Twitter to suggest she doesn't feel the same way, even alleging she was forced to call the police after an argument with him.

Take a look at an update from MTV News...

Steph's latest accusations come after she shared a photo to her Instagram Storyof herself crying along with Jonny's initials on Sunday. She later deleted the post, writing: "None of you know what my life is like, none of you know that I am not speaking to my family, none of you know that I ended up calling the police last night because I was terrified so f**k all of you."

At that point, she did not indicate that Jonny was involved with her decision to call the police.

On Thursday night The MiCstar began sharing screenshots of messages she had received claiming Jonny had cheated on her during a club appearance in Exeter,before going on to again claim she contacted the police, seeming to suggest it was over an argument they'd had.

In response to a message that claimed Jonny had cheated on her with two girls, Steph wrote: "I can't tell if I'm numb or in absolute shock..."

Steph then shared a screenshot of a message that suggested Jonny had attempted to buy someone's silence after he was unfaithful.

Things got pretty worrying as Steph then shared evidence of an "urgent" text she sent to her agent when "it went too damn far."

"I didn’t want to ever indulge more into my cryptic text abt calling the police- but now seeing his secret double life. WOW. My heart is just smashed. So much deceit & abuse. WHY. I’m not a bad person... why why why," Steph wrote after revealing she had been in contact with the police.

She vowed never to speak to "that monster" again.

Jonny is yet to comment on Steph's Twitter allegations, although during a Fubar radio chat earlier that day before Steph's posts, he said: "You do find that a lot of people are out to get you. People will try and sting you – the amount of times I’ve had people take a selfie with me and claim they’re on a night out with me."
