Married At First Sight's Lauren Dunn has revealed a major spoiler that will be revealed in an upcoming episode of the series.

The Perth-based PR guru and food blogger, 32, appeared on KIIS FM's Kyle & Jackie O show on Tuesday alongside her groom Jonathan McCullough, where she shared an X-rated confessional with “villain” groom Jack Dunkely hinted.

Lauren and Jonathan revealed that the 34-year-old personal trainer engages in “water sports” – a taboo sexual act – and that this will air at some point in the series.

'What?! Is that in the show? Do we see that on the show?' asked a shocked Kyle Sandilands.

'Yes. “It’s coming out on the show,” Lauren confirmed.

“It's going to be pretty wild. It's pretty crazy.'

Elsewhere in the interview, Lauren dropped several wild sex confessions of her own.

Lauren said she had never seen Jonathan naked before, having previously joked that she wanted a husband with a “big cock”.

“We’re not there yet,” she told radio hosts Kyle and Jackie “O” Henderson.

“I saw the bulge through my pants…It's a great bulge.”

The outspoken bride also revealed how many people she slept with before her MAFS appearance, admitting the number was “embarrassing” as she was mostly in long-term relationships.

“It’s an uncomfortable number because I’ve been in relationships for so long,” she said.

“Let’s say seven…maybe add some salt and pepper and you might get the actual number.”

Meanwhile, Kyle said women always halve the number of people they've slept with, claiming Lauren has actually had 14 sexual partners.

“They are not afraid of confrontation and have often been praised by producers for doing the show,” the spy said.

Lauren doesn't shy away from confrontation, as personal trainer Jack Dunkley found out on Monday's episode.

The groom was confronted with his relationship status outside of the experiment.

A woman named Courtney Jade claimed Jack ended their relationship under false pretenses to join MAFS.

But Jack defended himself by playing down his previous relationship as “casual yet exclusive” before dismissing Courtney as a “disgruntled ex”.

The conspiracy intensified when Jack accidentally revealed the timing of their breakup, which coincided with his involvement in MAFS.

Lauren Dunn expressed her frustration with Jack's evasion while speaking to the cameras.

“I feel like I'm going to resent this situation if he continues to be full of it,” she said.

Married At First Sight continues on Tuesday at 7.30pm on Channel Nine and 9Now.
