The reality stars come to blows on tonight's episode, and have to be separated by co-stars and security.
No wonder Marnie tweeted: "I don't think I can bear watching Geordie Shore tonight :( hate hate hate fights NEVER AGAIN :( love you char."
Charlotte replied: "NEVER EVER AGAIN! love you more than anything."
So, what happened?
Well, it all started at the club when Marnie decided to kiss newcomer Marty McKenna, who has history with her BFF Chloe Ferry. Chloe accuses Marnie of breaking 'girl code' and Charlotte has Chloe's back… thanks to the fact Marnie previously slept with Gary Beadle.
When Charlotte hears Marnie shouting at Chloe, she storms down to have her say. "All I can think about is Marnie shagging Gary," says Charlotte. "Let me at that b*tch, I am going to take her head clean off."
Marnie's attitude? "If you're going to come in my personal space Charlotte, you are going to lose some hair extensions, mate."
Oh dear. It all kicks off – literally – at 10pm on tonight on MTV.
