Gaz is thought to have hit out at recent reports that claim he bedded Jemma Lucy, as well as Olivia Walsh and Charlotte Dawson, while filming for the new fifth series of Ex On The Beach in Thailand.
In now-deleted tweets, Gaz reportedly responded to an article addressing the cheating accusations, saying: "You f**king kidding!! 'Boyfriend' since when were we boyfriend and girlfriend?
"Exactly we weren't!! So how can you say I cheated!?!?!? [sic]."
He then added: "And relax.... Rant over.... [sic]."
Gaz's rant comes after he took to Twitter last week, addressing his 2.29million followers, saying: "2 sides to every story remember that... I have found out a lot of important stuff over the last few weeks.. I'll explain all soon."
Charlotte had also revealed that she was "upset" about reports linking him to other girls on the show.
Although clarifying that Gaz wouldn't have technically cheated because they are both single and not committed to a relationship, Charlotte told Heat Radio: "I just thought that maybe it was going somewhere. We'd spent quite a lot of time together, he stayed at mine the night before he flew to Ex On The Beach... We'd had a lot of conversations where he had led me to believe that nothing was going to happen.
"It's something that I'm going to stay well away from and well out of. I don't want much to do with it at all."
Last week, Charlotte also appeared to take a swipe at her on/off beau on Twitter. She had favourited a tweet, which read: "It's very sad that an almost 30 year old is still living a "lad" lifestyle. @Charlottegshore I can't wait for you to move on to better things."
Before Gaz's EOTB stint, Charlotte said she would "100 percent commit" to him if he stayed loyal while he was away filming for the show.
"He's said that he's not going to do anything," she told us. "This is Gary we're talking about. I like the thought… but I really hope he doesn't.
"If he didn't then that would really determine what's gonna happen when he gets out. I would 100 per cent commit to him, completely. But it all depends on what's going to happen in there. That's the only thing that's been holding us back for so long."
