Gemma Collins is "raging" that James "Arg" Argent kept her his "dirty little secret".
The blonde beauty bedded her 29-year-old ex earlier this year and even admitted that she had unprotected sex with him to try and get pregnant but he's seemingly furious that she dished on their hook up.
A source said: "Gemma is raging. She's not some dirty little secret."
And Gemma, 36, is gutted that he is "saying" nasty things about her behind her back.
A source told Reveal magazine: "She never meant to cause Arg upset, and was very sad to hear what he's going around saying about her."
However, Arg - who was also suspended from "The Only Way Is Essex" in 2014 after testing positive for cocaine - has had a rocky few months after he took it upon himself in February to check into a rehab facility in Thailand while his ex-girlfriend Lydia Bright was competing on the winter sports show "The Jump" in Austria.
And last week, he was forced to deny on Twitter that he wasn't allowed to return to the current series of the ITVBe show because they were worried it would throw him back off the bandwagon.
He wrote: "I definitely haven't been axed & I'm incredibly grateful to my @OnlyWayIsEssex @ITVBe Family's who have continued to support me! #BeBackSoon (sic)"
The star was last seen on screens at the end of 2016 and it's believed show bosses are concerned that the pressure of appearing on the reality show could set him back.
A source told The Sun Online: "Arg loves "TOWIE" and was hoping he would make a cameo in the final few episodes of the series. But bosses believe after a lengthy stint in a rehab, being rushed back into the fold would not be in the best interests of Arg and other cast members.
"He was also told a full-time return is unlikely unless there was a dramatic improvement in his lifestyle."
