Fans will know Chloe has a huge soft spot for Marty and the pair have plenty of history together. During series 12, Marty was Chloe's ticket to getting over her feelings for Scotty T and so far on Big Birthday Battle, their romance has been hotting up.
However, Chloe finds herself lashing out when she hears Marty has been locking lips with Charlotte instead.
In next week's episode of Big Birthday Battle, Charlotte and Marty end up kissing while out working for Team Charlotte. Charlotte admits she got a little carried away at her team's S&M party and she ends up flirting up a storm with Marty.
Bad move, Char. Bad move.
Charlotte and Marty shock all their co-stars by tashing on, and everyone is on edge about how Gary Beadle will react. Viewers watched Charlotte and Gaz agree to start officially seeing each other, and the pair have been acting like a couple on the show.
So much so, that Gaz has said he is willing to commit to Charlotte and took her out on the pair's very first date.
However, the house seem to forget all about Chloe and Marty's romantic history. They had hooked up long before Marty joined Geordie Shore, and the pair recently had sex on the current series.
Despite falling out over Daniel Thomas-Tuck (Chloe had kissed him to get back at Marty pulling another girl when he said he wouldn't), Chloe admitted she still likes Marty. A lot.
She gushed: "I've never got on better with a boy in my life."
Not surprisingly, news of Charlotte and Marty's kiss gets back to Chloe and she lashes out. She says: "Charlotte and Marty have f**king kissed. Are you f**king joking us? What the f**k is she playing at? She's supposed to be my friend."
Chloe confronts Charlotte and says: "Charlotte! This has got to be a joke... I'll never, ever, ever, ever forgive you." Breaking down in tears, she adds: "Martin! Martin! I will never, ever forgive you for this. Never, ever."
To the camera, Chloe adds: "Charlotte knows how much I like Marty, so why the f**k would she go there? I would never do that to her."
Marty, meanwhile, admits he totally forgot about how Chloe would react. He confesses: "Chloe is going for us. I didn't even think about how it would affect her. She is raging."
Chloe not only lashes out at Marty, causing security to intervene, but she starts to smash up the house too, prompting Nathan to step in and try and calm her down.
Geordie Shore: Big Birthday Battle continues Tuesday 7 June at 10pm on MTV.
