Runaway Bride Shocks MAFS Producers with Secrets

Married At First Sight 2026 has already been rocked by mass meltdowns and production crackdowns.

But nothing sent producers into panic mode quite like the dramatic exit when model bride Brook Crompton wanted out.

Daily Mail can reveal the Queensland model, 27, abruptly quit the experiment just days into filming, booking a one-way flight home after clashing with production and triggering what insiders describe as a full-scale behind-the-scenes crisis.

At one point, EndemolShine bosses showed up at One Global Resorts in Green Square, where the show is filmed, to convince her to stay.

Brook's sudden departure came amid growing speculation she had secretly rekindled a romance with an ex-boyfriend during filming - allegations she has strongly denied.

Brook insists she did not reunite with her ex while part of the experiment and maintains any reconnection only occurred after she left the show.

'We were talking about wanting to have children, you know, I wanted someone mature who adores me for me,' she said of her ex, Harry, in an interview with Chattr.

'I had come out of a relationship where we were settling down. We were talking about wanting to have children, you know, I wanted someone mature who adores me for me.'

Despite the swirling rumours, insiders say Brook's decision to walk away had little to do with her on-screen marriage and more to do with how toxic the show was.

'She was actually getting along with her groom,' a well-placed source told Daily Mail. 'The issue wasn't the relationship - it was production. She hated being bossed around.'

According to sources, tensions escalated rapidly as the realities of filming set in, with Brook becoming increasingly frustrated by tight schedules, constant direction and the financial cost of being away from her real life.

'The pressure and the money she was losing just wasn't worth it,' the source said. 'She felt like she'd been promised one experience and got another.'

Matters came to a head when Brook quietly booked a flight home - despite being explicitly told not to leave.

'She didn't ask. She didn't negotiate,' the insider said.

'She just booked the ticket and left.'

Producers were reportedly blindsided by the move and immediately went into damage-control mode, scrambling to convince her to stay.

'They begged her,' the source revealed.

'They promised future opportunities and tried to calm her down, but she was done.'

Brook's exit sent shockwaves through the production, particularly given her strong on-screen presence and early promise as one of the season's standout brides.

'She's stunning, outspoken and fearless,' the insider said.

'Viewers are going to be shocked. She leaves a big impression, even though she walks away early.'

The runaway bride saga comes amid what insiders have described as one of the most turbulent seasons in the show's history.

MAFS bride at centre of explosive ex-lover scandal and pregnancy bombshell is finally exposed

As previously revealed by Daily Mail, the 2026 season spiralled into chaos during filming, prompting Channel Nine to introduce weekly drug testing, stricter curfews and a zero-tolerance approach to tantrums and walkouts.

Multiple contestants are believed to have threatened to quit throughout the experiment, while others were warned they would be in breach of contract if they walked.

'This season was an uncontrollable wildfire,' one production source said.

'Nothing could prepare them for how badly this group would behave.'

Despite the turmoil, insiders admit the chaos is also what makes the upcoming season so compelling.

'When Nine says this is the greatest season ever, they're not exaggerating,' the source added.

'It's messy, it's loud, and it's completely unpredictable.'

Whether viewers ever get to see the full story behind Brook's dramatic exit remains to be seen.

But one thing is certain - MAFS 2026 loses one of its most explosive personalities almost as quickly as it finds her.

And the experiment never quite recovers.

Crompton and Channel Nine did not reply when approached for comment.
