He's been fuelling speculation that he and Marnie are romantically linked again, and now it seems like it's Marnie's turn to send the rumour mill into overdrive.
Neither have actually spoken out about their relationship status, whether they're dating or if sparks have been flying, but a series of Instagram posts have been suggesting this might just be the case.
Taking to the photo-sharing app, Marnie posted an image of a mirror that had the words 'I adore you' written across it.
It was her caption, though, that really had us guessing. Alongside her post, Marnie simply added the word 'him.'
Him? Who's he? Aaron possibly?
Fans were quick to share their hopes that it is Marnie's co-star that has stolen her affections, with some suggesting Aaron had actually wrote the message himself across Marnie's mirror.
One follower commented: "Omg how sweet! Aaron's love letter to marns." While another said: "Aaron wrote this on her mirror."
Others seemed a little impatient with it all, they added: "Can they just admit they are a thing."
We hear ya!
Marnie's Instagram comes after she and Aaron were pictured kissing while filming overseas for Geordie Shore's thirteenth series.
Aaron has also been hinting that romance could be on the cards for the pair. He has shared shots from filming on his Instagram of himself and Marnie holding hands. He also posted photos of Marnie in just lingerie, referring to her as his "wife" in the caption.
Marnie hit back at the time and tweeted: "I ain't nobody's wife." And that left us all confused over her situation with Aaron, but something tells us this could be a case of watch this space.
Fans will be relieved to see the pair back on good terms again, as Aaron and Marnie had fallen out prior to filming. The pair had been dating, but Marnie accused Aaron of cheating on her (he denies this and hit back that she had told him they were not together) and the couple publicly fell out on social media.
Sounds like they've now kissed and made up, right?
