Eagle-eyed MAFS fans then identified Cameron to be the man at the centre of the cheating scandal after an editing mishap revealed his tattooed arm caressing a woman's leg in a trailer.
To top it off, back in October (five days after the first dinner party was filmed) Coco was photographed with Cameron, though she was walking a few steps ahead to avoid photos.
It wasn't until the second dinner party when the group learned of Coco and Cameron's connection.
Dressed in a risque bodysuit, Coco admitted that she was excited for Cameron to see her in her outfit but firmly denied that she and Cam had ever done anything that can be classified as cheating during their time in the experiment.
"I feel so embarrassed that people are insinuating that Cam and I are in a relationship behind their back. That's not the case at all and it's just hurting Samantha," the Pilates studio owner shared with the group.
Both Coco's husband Sam and Cam's wife Samantha gave their respective blessings at the dinner party but Cameron refused to acknowledge that there was anything there with Coco.
"I'm married at the moment so I've got to be respectful to my wife," he told the table.
However, a new trailer has emerged that features Coco and Cameron take their flirtation to a physical level.
In the teaser ahead of Sunday's Commitment Ceremony, Cameron pulls Coco towards him and the pair share a passionate kiss with *a lot* of tongue.
A source told the So Dramatic! podcast that Coco and Cameron kept their affair from the rest of the cast and no one found out until the final reunion when apparently "all hell breaks loose" and Coco doesn't come off in a good light.
Fans of the show are torn as to whether this affair is a legit one or fabricated by producers.
"Coco and cam look so staged, and i thought cam and sam were such a good match!" one person wrote.
"The old Coco & Cam betrayal... haven’t we seen this before?" another posted on Twitter along with a GIF of season six's Sam Ball.
Guess we'll have to wait and see what happens...
