After getting engaged while out in Greece last time round, Marnie had decided to leave Geordie Shore and focus on her relationship with her then fiancé Ricky Rayment. However, a few months after he popped the question, Marnie confirmed she was single again and made a beeline for the Geordie Shore house.
Yep, she'll be returning for the show's next series, but Marnie admits she didn't exactly get the welcome she wanted.
Instead, the 23-year-old was left fuming after finding out new girl Chantelle Connelly had made a lasting (and quite literally) impression on Aaron.
26-year-old Chantelle had hinted she likes a lad with tattoos and while we predicted she may take a liking to completely covered in ink Aaron, it turns out we may have just been right.
Marnie recently revealed in a new spoiler video shared by MTV that when she arrived back at the Geordie Shore house, she found out Aaron had added Chantelle's name to his body art collection.
A tattoo of Chantelle's name? That's a pretty big commitment, no?!
Marnie said: "The most shocking thing for me was when I walked back into the house and Aaron had the new girl's name tattooed on his wrist. I was furious."
That's not surprising, as Marnie and Aaron's relationship is almost as on and off as Gary and Charlotte's. The pair have been going round in circles since they first set eyes on each other, but it sounds like Aaron's new tat wasn't enough to keep Marnie away.
She has already revealed she and Aaron get close again this time round, and the pair even venture out on a date!
While we can't wait to see Marnie and Aaron's romance developing once again on screen, things haven't exactly worked out for the pair on the outside.
Aaron recently admitted he was left "gutted", after Marnie blew him out on Valentine's Day. Poor, Aaron!
He claimed he had planned a special date for the pair, which including booking dinner and a hotel room, but Marnie had already made plans with Ibiza Weekender star Jordan Davies instead.
Aaron said he presumed Marnie would be free, as the pair had been getting together, but instead she 'pied' him for someone else. Suggesting he is done with their romance, Aaron later tweeted: "The ship has sailed."
He also hit back at being labelled "desperate" after revealing his Valentine's Day fail, appearing to slam Marnie and Jordan while doing so.
Aaron tweeted: "Laughing my head off some 1 calling me desperate when they are the 1 that went on a date and took the paps with them."
