You can predict her reaction, right?!
In next week's episode of the MTV show, we'll see Marnie making a surprise return to the house after previously quitting the show following her engagement to now-ex fiancé Ricky Rayment.
While everyone is thrilled to see her, no one is as excited as Aaron, who says: "Me and Marnie had always had chemistry but it just never worked. When she got engaged I thought that was it. But now she's back and she's single I am f**king buzzing."
But his buzz may not last long!
That naughty housemate Scotty T - or "c**k block", as Gaz calls him - decides to break the news to Marnie that Aaron had Chantelle's name tattooed on his arm in a bid to woo her when she was getting attention from both him and Scotty.
So, so naughty!
"Maybe I shouldn't have mentioned anything but soz Aaron, survival of the fittest," said Scotty.
"What the f**k?" was Marnie's reaction. "Why would you do it?"
Off-camera, Aaron said: "Because you were engaged, I wanted to pull Chantelle and get one over on Scott. But f**king hell, I regret it now, like."
