Taking to the streets of Newcastle with her Geordie Shore cast mates, Marnie brawled with fellow star Chloe Ferry in the early hours of Tuesday morning.
The former finance of Ricky Rayment was seen staggering out of a local nightclub, before the incident kicked off between her and Ferry.
And although it isn’t clear exactly why the pair were fighting, some reports suggest the girls fell out over Geordie Shore newcomer Martin, who was also out that night.
Meanwhile, Holly Hagan and Charlotte Crosby put on a more civilised display as they hit the town, both donning figure hugging trousers and revealing tops.
Former Geordie Shore star Vicky Pattison, who left the show last year to pursue other projects, was meanwhile half way round the world - in Australia - as she takes part in this year's I'm a Celeb contest.
