The Only Way is Essex couple were rumoured to have split following a series of arguments.
Sourced had previously told The Sun that she had become "fed up" of the constant rowing between the pair.
"Arg also went to Ibiza a few weeks ago and didn't take Gemma, which infuriated her," the source claimed.
However, a spokesperson for Collins dismissed the rumour, stating that their relationship is still currently on.
A representative told the Daily Mail: "They are always on & off but are currently still together."
Collins accused boyfriend Argent of cheating on her on Twitter last month.
Earlier this month, Collins also reacted angrily to photographs of Argent on a night out with Inbetweeners actress Emily Atack.
She said at the time: "My boyfriend Arg was seem flirting with actress Emily Atack at the Playboy club in Mayfair when I thought he was going to be coming out with me.
"I felt really upset about the whole thing. I didn't cry, but I just think it's downright rude. He's told me nothing happened between them but he was in my bad books regardless."
Gemma Collins recently hinted that a movie version of The Only Way is Essex in in the works.
