It’s another chaotic episode of “Geordie Shore” on Tuesday, as fan favourite Marnie Simpson makes a big comeback. The gang is not shy in making her feel at home right away, but not everyone is happy with her arrival. Right at the start, things become awkward between Marnie and newbie Chantelle Connelly, and it’s not too long before the two find themselves in an explosive argument over Aaron Chalmers.

On April 11, the gloves come off for another girl fight, and their friends could not help but get involved. Fans are wondering about the reaction of the other members of “Geordie Shore,” including Chloe Ferry, Holly Hagan, Charlotte Crosby, Gary "Gaz" Beadle, Scott “Scotty T” Timlin, Nathan Henry and Marty McKenna.

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 the preview video, the Geordie Shore gang arrives home and gets the surprise of the season when Marnie appears. Mayhem ensues as they squeal in delight and the ladies rush on top of the stairs to welcome her back. Speaking to the cameras, Chloe can’t contain herself and she screams, “Oh my f---ing God, Marnie’s back!”

Marnie also speaks to the cameras as she recounts that the last time she has seen her fellow Geordies was in Greece. “I got engaged but that didn’t work out,” she says. “The engagement is off, and I’m single.”

She wastes no time sharing this bit of news to everyone, eliciting yet another series of squeals. Fans wonder whether Marnie’s newfound singlehood would translate to rekindling her love story with Aaron. The Geordie lad opens up to the camera that they have always had chemistry, but it never flew and then she got engaged. He wonders what will happen now that Marnie is back and is single again.

However, there is that little obstacle, named Chantelle. There’s already an air of tension when Marnie gets introduced to Chantelle. Marnie, who gives her a dismissive nod, reveals to the camera how she feels exactly about the new girl. “She’s trying to be me,” Marnie says. Things become more complicated when Scotty lets it slip that Aaron got a tattoo of Chantelle’s name on his wrist. “You never got a tattoo of my name,” Marnie says. To the cameras, Aaron replies that it’s because she got engaged and he moved on.

Another preview shows how hell hath fury like a woman who got dissed. Marnie lashes at Chantelle, and the Geordie girls are quick to side with the original member. Marnie tells Chantelle that Aaron will never be with her, and called her a victim. Chantelle retorts to the camera, “If I’m the victim, why does Aaron have my name on his tattoo?” Meanwhile, Aaron vents his frustration and turns his rage on to the innocent red phone booth.
