Viewers saw the housemates separated by security and co-stars on Tuesday night's episode (26 April) after coming to blows during a drunken evening.
It all kicked off when Marnie snogged new boy Marty McKenna at the club, which infuriated her BFF Chloe Ferry, who has history with Marty. Charlotte then got involved to defend Chloe and because she's still sore about Marnie sleeping with Gaz Beadle in the past.
Speaking to the Confession Cam, Charlotte said: "I'm really gutted about what happened last night. Me and Marnie got into a massive, massive full-scale fight, probably one of the worst the house has ever seen."
"It's done now," she added the next morning. "I got a shock when I saw Marnie flirting with Marty because it was out of the blue. And I think Chloe got a shock too. I know how much Chloe likes him and I think she expected Marnie to know that too as they're closer friends than me and Chloe. It all escalated, there was way too much drink involved, and I totally regret it.
"I only hope we can resolve it very soon."
Well, she got her wish as Marnie tweeted today: "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."
