Facebook and Twitter users reported that the 22-year-old TV star was hit after visiting Pharaohs bar in the Lancashire town on Saturday (September 22).
Essex had been in the area hosting an evening called 'The Only Way Is Reem' at local club Fusion.
The Sun reported a witness saying: "He was going across the dancefloor when someone side-swiped him. He fell on the floor. Joey didn't know what hit him."
However, Essex's spokesman Dave Read told the newspaper that the reality TV personality had "laughed" at reports he was hit.
Read said: "Joey went in the bar, but is adamant he was not hit. Someone's trying to stir things."
Essex's fellow TOWIE cast member Gemma Collins was recently quoted as saying that a movie version of ITV2's structured reality show is in the works.
