Has MAFS' Charlene moved on with co-star Matty?

It seems this has been the year of wife and husband swapping on Married At First Sight.

First there was that whole affair with Dean Wells and Davina Rankin and then Dean's wife Tracey Jewel ran off with Sean Thomsen.

Troy Delmege and Carly Bowyer are off laughing hysterically and very loudly into the sunset together and their "exes" Ashley Irvin and Justin Fischer are now hooking up.

But it doesn't end there. We have a sneaky suspicion Charlene Perera and Matty Lockett are now potentially an item.

• MAFS' Carly 'can't breathe' when Troy kisses her

• Inside Sarah and Telv’s explosive breakup

The pair recently met up in Melbourne for a cheeky steak and chips. If that doesn't scream couple alert, we don't know what does.

However, Matty appeared to joke they were attending a "#swingers" together on his Instagram. Er, interesting.

They also dabbled in a bit of a carpool karaoke on their outing, date, meet-up, whatever you want to call it.

But the clue is in Matty's hashtag on the video, #treatthemdeankeepthemkeen. You want Charlene to be keen then, Matty?

Fans were also quick to ask if they were together in the comments on Instagram.

"Wait what's happening? Are yous two friends? Or together?" one commented.

Many other comments followed the same tune with a lot of "huhs" and "whats".

Matty insisted to the Daily Mail Australia he and Charlene are "just mates". Hmmm, we shall see.

What would their former partners Patrick Miller and Alycia Galbraith think?!
