James and Danielle were shown on Wednesday night having a foul-mouthed argument with Gemma and her pal Bobby Cole Norris after things kicked off at James 'Arg' Argent's food party.
Bobby had previously told Danielle that he'd heard James had cheated on her, however she has chosen to believe her man.
During the row, Danielle called Gemma "fat" and, although she now regrets using this word, James isn't ready to kiss and make up with Gemma just yet.
Speaking at last night's premiere of The Stag, James told Reveal: "Gemma is just a busybody.
"She involves herself in everything and she should just look after herself really. I don't need a fake friend like Gemma. She's a big voice with no substance."
Although she apologised on Twitter for calling Gemma "fat", Danielle is standing by the other jibes she used - including "silly b*tch".
"She deserved everything else I called her!" Danielle added, while chatting on the red carpet in London's Leicester Square.
Meanwhile, although she is standing by James, Danielle says he has his work cut out before she is ready to fully trust him.
"He's got to prove to me I can trust him again," she admitted. "He's halfway there, but I have to stand my ground and have a little bit of girl power."
Danielle, who didn't leave her boyfriend's side at the event, also confirmed that she has now put house-hunting with James on hold due to the rumours.
"The biggest thing for me is that I've known James for five to six years and we dated before going onto the show," she continued.
"The whole situation has been awful and I've been really upset, but we're for real. This isn't a showmance."
James added: "A lot of the TOWIE cast are insecure and when their relationship even touches the show, it just crumbles. I think we've got the strength to get through this."
