Fassbender was said to have been asked to leave after becoming "a bit of a handful" at the glitzy bash, hosted by the men's magazine following the premiere of A Dangerous Method in London on Tuesday.
A source told The Sun newspaper: "He was grabbing his co-stars and waltzing around the room with them. He lit a cigarette indoors and that was the point it had gone too far."
But Olivia Cole, a literary editor for GQ, has taken to her Twitter page to set the record straight.
She writes: "Dear (journalist) Gordon Smart of The Sun your story about Michael Fassbender at GQ's party on Tuesday is complete fiction. Check your facts. We were glad he was there and no one was asked to leave early, but hey, feel free to just make it up."
