The Love Island rapper claimed that he received numerous flirty messages from the mum of five, but said he never replied.
But Katie is said to have revealed 52 screenshots from her Snapchat at her book launch which reportedly prove Chris did respond to her.
In one message, 24 year old Chris is reported to have called girlfriend Olivia “fame hungry” and accused the blonde of “loving publicity”.
But Olivia clearly wasn’t fussed by the ongoing spat, instead making light of the situation.
After seeing Chris was being urged to dump her by a Twitter user, she responded: “LOL please don’t dump me baby.” The blonde later shared a gif showing Britney Spears yawning.
Katie is reported to have claimed that the messages dismiss the idea that she is “bitter” or “pied off” – as Chris previously alleged.

She also said that she won’t be publicly sharing the screenshots like Love Island star Chris did.
But Kem Cetinay’s BFF shared an expletive-filled statement his 430k followers that he “couldn’t give a s***t” who he offends.
“I stand on my own and always will, I don’t need people to get me,” Chris began the lengthy post – he has since deleted – on Twitter.
“Katie Price you’re a rotten piece of s***t. I couldn’t give a f**k about you. Be a mother, be something respectful for everyone’s sake. I showed you’re [sic] true colours, you couldn’t live with it.
“You have 52 screenshots on Snapchat since I humiliated you? Comical. I’ve got my whole account history from Snapchat and a media lawyer will f*** you up.
“No one deserves your s**t, and I ain’t one to take it. You f**k lives. You have MY number, you can see I haven’t ever sent you s***.”
