We're only the second week into Married At First Sight and there's already a rumoured cheating scandal on our hands.

Are we surprised? Absolutely not. Are we still shamelessly invested? Yes, yes we are.

This time around, the cheating scandal is rumoured to involve the 32-year-old crane operator Cameron Dunne and 30-year-old pilates studio owner Coco Stedman.

Watch the trailer for the current season of Married At First Sight. Post continues below.

Those who have been following the show will know that Cameron has been matched with bride Samantha Harvey. And things started off pretty great between the pair... that was until their honeymoon.

Thanks to the good ol' trusty honesty box, Cameron told Sam that she wasn't his type and had no "emotional connection" to her, despite sleeping with her the night before.

Now, it appears Cameron is interested in a very different bride.

"I mean I would have been happy to be matched with you," Cameron tells Coco in a trailer for tonight's episode.

Already keen to do it all again," he wrote on Instagram alongside a photo of himself looking very tanned and buff.

When it comes to dating, Cameron told Channel Nine that he's used to being put in the "friend zone" but he also "self-sabotages" due to "trust issues after being cheated on in the past"....interesting.

While his relationship history remains a bit of a mystery, the 32-year-old was linked toSAS Australiacontestant Arabella Del Busso, who previously dated NRL player Josh Reynolds.

Earlier this week, Arabella told Woman's Day that she's known Cameron "for 10-plus years".

"He's such a lovely person and down-to-earth," she added.

When asked if the pair had any romantic history, she responded, "I can't kiss and tell..."
