For the last few years, Marnie and Aaron's romance has been on and off, and fans had been hopeful that the pair were going to make a go of things, after they were spotted getting close during filming for Geordie Shore's thirteenth series last month.
Aaron and Marnie had fuelled speculation they were dating again, but Marnie later insisted she is "single" and has now moved on with former TOWIE star Lewis Bloor in the CBB house. However, she did admit that, despite her romance with Lewis, she still has feelings for Aaron.
Marnie spoke of an 'ex-boyfriend' she has on Geordie Shore (fans were quick to link her comments to Aaron), when Aubrey O'Day asked her if she could go back on to Geordie Shore and not hook up with anyone.
Marnie said: "I don't even know if I'd want to put myself in that situation, because even though the way I feel about Lewis, there is an ex-boyfriend on there who I have always had feelings for and just being in that environment where I'm drunk, I don't know what I'm doing... you've heard some of the crazy sh*t I've done."
Renee advised Marnie: "Don't give up your day job until you're 100 percent sure."
Following their conversation, many fans were quick to tweet Aaron to see what he made of Marnie's comments. One Twitter user said: "Why is Marnie talking about @AaronCGShore on #CBB hahaha."
Aaron replied asking what had been said, as he hadn't been watching. The user tweeted him back: "@AaronCGShore on about her and Lewis being a couple saying she couldn't because of GS and her ex that's she's always had feelings for haha."
Aaron responded: "Awkward she ain't coming back to me."
Aaron had previously ruled out any future romance with Marnie, following speculation that her relationship with Lewis is a 'showmance.'
CBB viewers had been questioning the authenticity of Marnie and Lewis' romance, leading one confused fan to tweet Aaron saying: "I thought she was with you?"
Aaron replied: "Defo not with me and never will be (sic)."
While he and Marnie had been 'inseparable' (according to Gaz Beadle) before her CBB debut, Aaron has wished Marnie well and told fans she is free to do 'whatever she wants' on the show.
Viewers have seen her fall for Lewis in the house, with Marnie and Lewis recently telling each other they are in love.
They have also been discussing their future as a couple on the show, and Lewis has ruled out an appearance on Geordie Shore alongside Marnie. He also told her that 'love comes first before money' and that he wouldn't be interested in the pair having their own spinoff show - not unless they were paid £1 million for it.
CBB airs nightly on Channel 5.
