Charlotte and Marty KISS?! Well, we can't say we ever saw that one coming...
At the end of last night's episode, MTV gave fans a little taste of what's to come and it all kicks off between Charlotte, Gaz and Chloe.
We're not quite sure how it happens, but during one of the gang's Team Charlotte and Team Gaz nights out, Char and Marty end up locking lips. Next thing you know, she is seen in tears as an emotional and angry Chloe tells Charlotte: "I will never ever forgive for you this."
Fans will know that Chloe and Marty have been getting together on the show, and despite their fallout over Daniel Thomas-Tuck last week, Chloe had admitted to liking Marty.
She said: "I do like Martin a lot. I've never got on better with a boy in my life."
Gaz, meanwhile, is just as unimpressed. While the teaser didn't show him confronting Charlotte about the kiss, he is seen telling the camera: "We are done" - just seconds before telling Charlotte he wants to be her boyfriend.
Throughout Big Birthday Battle, Gaz has been telling Charlotte he wants to give their relationship a go. The pair had agreed to officially start seeing each other and Gaz even took Charlotte out on their first official date.
In last night's episode, viewers watched Charlotte express her concerns over her blossoming romance with Gary once they leave the Geordie Shore house. He, however, told her things would only get more serious and said Charlotte would become his girlfriend - if she wanted to be, that is.
So, there's no way that kiss with Marty is going to go down well...
Geordie Shore: Big Birthday Battle continues Tuesday 7 June at 10pm on MTV.
