Former Married at First Sight contestant reveals secrets of filming arguments

A former Married at First Sight (MAFS) star has dished the dirt on what really happens behind the scenes when a married couple are fighting.

The chaotic reality dating show in which two people are 'locked in' by experts and then meet for the first time at the altar before exchanging vows is famed for its many explosive spats.

Many viewers have been left wondering what it's really like to argue with somebody with cameras and entire crew just inches away.

How real is it? And can you really say exactly what you think with the possibility of someone yelling 'cut'?!

Well, Tahnee Cook, who starred on Married at First Sight Australia's season 10 (yep, we just can't get enough of this show), has spilled the beans.

On the show, Tahnee was matched with Ollie Skelton, and the two went from strength to strength.

They renewed their vows in the final episode as an ultimate act of loyalty before calling it quits after 16 months of dating in the outside world.

Viewers were so heartbroken as it appeared they'd nailed it.

Tahnee, appearing on Yahoo Lifestyle's podcast Behind The Edit, revealed that 'diary cams' exist on the show so that the contestants can fill producers in on potential extra footage in case they want to film a scene.

An example being that in a past episode, fellow contestant Ellie Dix filmed herself speaking to the camera after an argument with her husband Ben Walters after he mocked her voice.

Tahnee spilled the cast are encouraged to use this as their own filming tool in order to fill the production crew in on the tea aren't following them around.

That way, producers can spring to film a brewing argument.

So it turns out that some on screen fights are very genuine, while some may have been tipped off by a contestant.

Tahnee said: "So the rule was if you start fighting you have to pull out your diary cam and film it." She then emphatically added: "Absolutely not happening!"

She continued: "Anytime you'd have, like, some sort of heated discussion or anything important, you'd pull out your diary cam, obviously we saw Ellie pull hers out and do her little thing. You'd have to do that, but not many people did.

"Usually, especially for things like the commitment ceremony, you're going to go home, no cameras there, and you're going to have a little bit of a debrief."

Tahnee then filled us in even further.

She said: "Then in the morning, you kind of have to do it again. They have to mic you up, then walk in, so it's not natural. The only time they really barged in the room was the retreat where we weren't mic'd up, that's the only time they came in with no notice... any other time, you get a bit of a pre-warning.

"So that's when you see them [the participants] tense, they've obviously had a discussion off-camera, and then things are tense and they try and bring the cameras in but most of the time it doesn't get caught on camera."
