Last night (28 July), CBB kicked off for another series and this time Marnie is doing it for the Geordies. She's taking after Charlotte Crosby, Ricci Guarnaccio and Scotty T and Aaron has got high hopes that Marnie is going to "smash it" just like they did.
Taking to Twitter, Aaron gushed over Marnie and said: "So proud of this little beauty going in CBB tonight!! Smash it and enjoy it gorgeous!!! I'm gna be your number 1 fan (sic)."
He and Marnie have been romantically linked in the last few weeks, after pictures emerged of the pair kissing and holding hands while filming for Geordie Shore's thirteenth series.
Aaron had fuelled rumours he and Marnie were back on again, as he re-posted them to his Instagram page and had referred to Marnie as his "wife" on the photo sharing app. Marnie, meanwhile, appeared to gush over Aaron, sharing a post that included the caption: "I adore you."
However, she recently cleared up that the pair are both "single." Addressing speculation her romance with Aaron was back on, Marnie said: "Aaron and I have serious trust issues, which is why we can't be together. I don't think he trusts anyone.
"I have my issues as well, though," she added. "We both need to work on ourselves before we can have a relationship. He'll always have a place in my heart, but we need to be single for now."
Judging by Marnie's VT, she definitely isn't ruling out an in-house romance while she's in the CBB house.
She told viewers: "I'm definitely not a sl*g, I wouldn't say I'm a nun either... I'm somewhere in the middle. I've got strong opinions, I don't like being told what to do and I don't back down. I am bisexual, so if there are any good-looking girls in there, I'll definitely be after them as well as boys... I am definitely after some fun, and that's what I'm going to get."
After Aaron's sweet message to Marnie for doing the show, many Twitter users were quick to point out what Marnie had said in her VT. When one claimed that Marnie had publicly dumped Aaron on TV by suggesting she wants to find someone on CBB, Aaron was quick to hit back.
They had tweeted: "Imagine finding out you've been dumped over national television though oh Hun."
Aaron responded: "How can I be dumped if we both single?" And added a crying with laughter emoji.
So he won't mind if Marnie is seen getting her flirt on with somebody new? Something tells us he might... just a lil bit!
She joins the likes of Ex On The Beach star Stephen Bear, Lewis Bloor, EastEnders Ricky Norwood and X Factor's Katie Waissel and Chloe Khan in the house.
CBB airs nightly on Channel 5.
