Recently, Aaron has made headlines for revealing Marnie had 'pied' him on Valentine's Day to head out with Ibiza Weekender star Jordan Davies instead.
He claimed that he is now done with his co-star (despite their on/off romance) and, after being labelled 'desperate' - although it is unclear who by - Aaron has laughed such comments off, suggesting Marnie and Jordan are instead.
He tweeted: "Laughing my head off [at] some [one] calling me desperate when they are the [one] that went on a date and took the paps with them."
Aaron added several laughing emojis to his tweet.
Both Marnie and Jordan have kept quiet on their own Twitter accounts, but fans were quick to link Aaron's tweet to the pair. One follower said: "What.... MarnieGShore?"
Another showed their support for the reality star, commenting: "Shaaaaade, go [on] aaron."

Aaron's tweet comes after recent reports revealed he had planned to take Marnie out for Valentine's Day himself.
The romantic holiday came around shortly after he and Marnie had wrapped filming for Geordie Shore's five year speical, and as they were getting together in the house, Aaron had presumed Marnie wouldn't have made plans with anyone else.
He soon found out about her date with Jordan and while he admitted he was a little bit gutted, he did suggest there were plenty of other girls he could turn his attentions to.
Reiterating that he is moving on, Aaron had cryptically tweeted last night: "That ship has sailed."
After making her Geordie Shore return (Marnie had initially left the show following her engagement to Ricky Rayment), Marnie returned to the house several weeks after she and Ricky split.
At the time, she and Aaron had sparked romance rumours and the 23-year-old recently revealed the pair did rekindle their romance.
Marnie has admitted she finds Aaron "annoyingly addictive." Opening up about her co-star recently, she said: "I hate him, but I love him. There's something annoyingly addictive about him. I wish I could shake it, but I can't."
