Married At First Sight 'wildest bride ever' accidently flashes her underwear in shock new trailer as Channel Nine teases season's most explosive contestant

Married At First Sight has shocked fans with a new trailer to promote the upcoming season. 

The show's 'wildest bride ever' Gia Fleur flashes her underwear in a jaw-dropping moment. 

The latest promo gives viewers their first proper taste of the chaos to come and wastes no time making it clear that modesty will not be on the agenda this series.

Gia is seen strutting down the aisle in a daring white wedding gown that leaves little to the imagination.

Things then turn chaotic after a sudden gust of wind lifts the fabric and exposes her underwear.

The moment comes just seconds after viewers are teased with the arrival of several other headline-making cast members, including bombshell bride Alissa Fay, controversial groom Chris Nield, and bride Rachel Gilmore.

'I am taking the biggest risk I've ever taken, I've ever taken,' Alissa says nervously in the clip.'Breathe. Oh my God.' 

The trailer then introduces groom Scott McCristal's best friend and former Bachelor star Paige Royal, who raises eyebrows with a blunt warning ahead of his wedding day.

Scotty doesn't like girls that swear a lot,' Paige confesses.

Moments later, Scott's bombshell bride Gia is shown making her unforgettable aisle entrance, her plunging gown and leg-baring silhouette stealing the spotlight before the wind does the rest.

The drama does not stop there.

Controversial groom Chris then delivers a shocking remark that is sure to ignite backlash before the season has even aired.

'If I turn around and see a short, overweight blonde girl, I'm gone,' he declares.

A producer quickly challenges him, asking, 'What if she's not into you?' The overconfident groom laughs it off. 'Please, please.'

But karma appears to strike just as fast. In a sharp tonal shift, Chris is later seen pleading with producers. 

'At least kiss me on the wedding stand,' he moans. Poor Chris.

Gia is already shaping up as one of the most explosive, divisive and talked-about brides in MAFS history.

Channel Nine sent shockwaves last week after dropping a teaser ad that introduced Gia as a bride who has zero intention of playing nice, staying quiet or shrinking herself for the experiment.

'My husband, he's gotta keep up with me. I will keep him on his toes. I'm not easy, but with men, I always get my way,' Gia declared. 

'It's easy to know why. Beautiful fake tits. He's gonna listen to me, isn't he?'

From the outset, Gia made it clear she sees herself as the dominant force in her future marriage, proudly embracing her fiery heritage and unapologetic confidence.

'I am a typical Italian. I could be a bit spicy a bit. Crazy. And I definitely take pride in my appearance,' she said.

For Gia, glamour is non-negotiable, even before sunrise. 

'I'm up at 6:00 AM looking like a Barbie. That's, that's it.' 

But it was her brutally honest take on how other women view her that lit up social media within minutes of the ad airing.

'Other women  are like, oh, look at her. Like stuck-up b***h. Like, why is she, why does she feel the need to have her tits out?' she said.

Her response was blunt, defiant and guaranteed to divide viewers.

'Like, 'cause Karen, I wanna have my tits out. What's wrong with that? Like, I don't care. I don't give a s**t.'

The teaser confirmed what insiders and early buzz have been pointing to for months.

Gia is not just a big personality, she is part of a powerful group of women who will fundamentally reshape the social hierarchy of the experiment.

Relationship expert John Aiken has already flagged the emergence of what he calls the 'self-proclaimed boss babes' this season, describing a dominant female alliance unlike anything the show has seen before. 

'I think it's the dynamic of the women in the group,' Aiken explained. 'The self-proclaimed boss babes that come together are incredibly dominant in the experiment. They call both men and women out, and sometimes the language is incredibly confronting and at times very hurtful.' 

According to Aiken, the scale of this power shift is unprecedented.

'I don't think we've ever had that group dynamic. In the past we've had one or two women that might clash, but we've never had this group of boss babes just coming in and really dominating.'

He revealed that the dominance of this alliance left many of the grooms genuinely shaken.

'This year, while we matched very strong-willed men with the women, what we found is that they were quite shocked at times by how this group reacted and how they spoke to certain people,' he said.

'As a result, some of the guys became more observant. They sat on the side, watched what they said and how they acted, because they were genuinely confronted.'

Aiken admitted the dynamic was never planned.

'We didn't know this would happen,' he said. 'What we wanted were empowered, vocal women. But the group came together organically. They met at the hens night and it really went from there.'

As filming progressed, the behaviour escalated. 

'I just remember thinking at the dinner parties, I don't think they've ever been this hostile,' Aiken said. 'Some of it was horrific. You really have to buckle up for this season.'

Sexologist Alessandra Rampolla echoed those warnings, confirming the chaos was not driven by one villain, but spread across the entire cast.

'This is now my sixth year doing the series, and I can look back at some seasons where one or two participants maybe carried most of the load of the drama,' she said.

'With this cast, it's really spread out. It's not just one person doing all the drama. Many of them have many explosive situations throughout the season.'

Alessandra described the 2026 brides as particularly volatile.

'A lot of the brides this year are very feisty, very combative and bring a lot of drama,' she said. 'You mentioned the word toxicity. There is some of that.'

She added that even the experts were taken aback once dinner parties began.

'They're lovely during casting. They speak to me, they have it all together, they're hopeful,' she said. 'And then you watch them interact at the dinner parties and sometimes I wonder, who is this person? I spoke to you a few months ago.'

The result, both experts agree, is a season defined by confrontation, dominance and blurred lines between honesty and cruelty.

'That's the conversation people at home will be having,' Aiken said. 'When is it okay to use vile language? When is it honesty, and when is it offensive?'

Married At First Sight returns February 2nd at 7.30pm on Channel Nine.
