Charlotte Crosby just might have ruined what could be something serious with her and Gary “Gaz” Beadle. Things get carried away and go horribly wrong after a night of fun and flirtation in “Geordie Shore: Big Birthday Battle.”

On June 7, Charlotte and Marty could not get their hands off each other during Team Charlotte’s S&M-themed party. The pair is soon engaged in a full-blown make out session in the full view of their teammates, who are completely stunned. It doesn’t take long before Charlotte got a dose of reality, however. After their kiss, she immediately goes to a corner and beat herself up for what she has done.

Back at the house, Charlotte and Marty’s liplock instantly becomes the headline for the night, eliciting shock among the o ther cast members of “Geordie Shore,” including Team Charlotte’s Aaron Chalmers, Daniel Thomas-Tuck , Holly Hagan , James Tindale and Nathan Henry, as well as Team Gaz’s Marnie Simpson, Chantelle Connelly , Jay Gardner, Ricci Guarnaccio and Sophie Kasaei. Whilst everyone is wondering how Gaz would react, they forget about Chloe Etherington, who has her eyes on Marty all this time.

Spoiler alert! This update contains more "Geordie Shore" spoilers. Read on at your own risk if you have not watched the latest episode.

MTV has posted sneak peeks [watch below] of the reality show’s fifth episode, which is due to air on Tuesday night. In one of the preview videos, Charlotte and her team are seen sporting skimpy leather and lace outfits for their S&M party. She admits to the cameras that their theme for the night is having a weird effect on them. “I’m a bit tipsy, I’m a bit h--ny, and I feel anything could happen,” she confesses.

On one side, Charlotte and Marty are seen getting a little bit intimate, and their friends are starting to notice. At one point, Charlotte and Marty go into full-blown flirting, as they talk about their private parts. A moment later – to everyone’s shock – the two are kissing. Scotty, Holly, and the rest of the gang could not believe their eyes. Holly wonders to the cameras, “She’s finally in a good place with Gary, and what does she do? Ruin it all.” Despite being clearly drunk, Charlotte could still tell she’s in for a big trouble. She admits that she has “f--ked up” and says, “Gary is going to f--king kick off.”

The other teaser shows everyone back at the house, as they talk about Charlotte and Marty’s lip lock. Their immediate reaction is about how Gaz would feel when he finds out. They are oblivious at first that Chloe is also there, learning that her friend just hooked up with her man candy. She goes around the living room to make sure she heard right.

She then goes to find Charlotte and confront her. “This has got to be a joke,” Chloe tells her. Charlotte apologises profusely, but Chloe is not hearing any of it. “I’ll never ever forgive you,” Chloe says. To the cameras, Charlotte shares, “I feel so awful. I’ve never done this to a friend, and seeing Chloe this upset is breaking my heart.

Upset may be too tame a word to describe what Chloe’s feeling at that instant. She goes to the girls’ room and starts trashing the place, absolutely furious. Nathan comes up to calm her down, but she’s on a roll, throwing things around and even hitting the mirror. She then lunges at Marty, who’s completely taken aback by her reaction. Chloe’s absolutely livid, she even threatens to leave “Geordie Shore.”

MTV reports that the Newcastle lads and lasses are now in the Mediterranean to start shooting for the upcoming season.
