It comes after The Block saw its lowest point play out on national TV when contestant Kylie locked horns with fiery host Scott Cam before fleeing barefoot into the night.

The 37-year-old hairdresser had her seven-year marriage to Brad implode on-air when the Cairns-based tradesman, 32, told fellow contestant Mimi Belperio he would ‘follow’ her OnlyFans account if she had one.

And on Sunday night, during the final round of judging, tensions reached a boiling point when Kylie took her fury out on the face of the series, Scott, 61, and earned his wrath in return.

After a gruelling week working on the exterior of House 4, Kylie and Brad were met with criticism from the judges who pointed out their front yard seemed unfinished.

Shaynna Blaze noted the outdoor area required ‘more thought and planning’, while Marty Fox commented it felt like they’d ‘checked out’.

A tense exchange erupted between Kylie and Scott during the feedback when the mum-of-four interjected, ‘Alright, let’s wrap it up,’ as Scott read the judges’ critiques.

When Scott replied, ‘What’s that?’ Kylie doubled down and fumed, ‘I said, wrap it up,’ as her husband Brad attempted to cut her off.

Stunned by the outburst, Scott arced up and said: ‘Kylie, I’m not going to wrap it up, because this is part of the deal, unfortunately.’

‘We’re reading out feedback, and it’s the last feedback you’re going to get from these judges on your house.’

‘I really couldn’t care,’ Kylie tried to interrupt, but Scott spoke over her in a rage, adding: ‘So I’d really appreciate it if you didn’t tell me to wrap it up.’

Kylie became visibly teary over being dressed down on national TV and muttered under her breath: ‘I f**king hate this guy.’

Scott continued to read out the judges critiques, which ended on a positive note saying the couple should be proud of the home they designed.

But the damage had been done as Kylie fumed the feedback was a ‘f**king joke’ just moments before filming went off the rails as she fled the construction site barefoot in the dark.

The explosive episode reached a climax when the judging results placed Kylie and Brad in fifth place with 26 points out of 40.

As the other contestants celebrated the week’s winners, Courtney and Grant, Kylie immediately stormed out, followed closely by Brad.

A frustrated Scott Cam attempted to call them back, only for Kylie to threaten to ‘break the f**king camera’ if the crew kept filming her.

Heels off, Kylie picked a direction and began walking off into the night down the middle of the road as crew continued to follow, begging her to return to set.

But Kylie refused, telling them she would start running if they didn’t leave her alone—a promise she made good on seconds later.

‘She is legging it, barefoot, down the middle of the road. We need a producer and a car, NOW,’ one crew member said as Kylie ran into the dark out of view.

What followed were panicked scenes of Brad setting out in a car with two producers in an attempt to find his wife.

They found her sitting on the side of the road in the dark in what producers described as a ‘scene from a horror movie’.

After Kylie was coaxed back into the car with her husband, Kylie sealed her promise to boycott auction day, even if it means forfeiting any potential profits from her time on The Block.

‘I don’t want to come back for auction, I don’t want to come back and have to deal with them. I don’t,’ she said.

The astonishing scenes come after Kylie split from her husband Brad on national TV last week, following his flirtatious comments to fellow contestant Mimi Belperio.

The couple, who share four children together, saw their relationship implode when the plumber told Mimi, 28, he would ‘follow’ her OnlyFans account if she had one.

Kylie sensationally quit the show after the flirty exchange and flew home to Cairns, only to return to the Phillip Island construction site on Wednesday to dump her tradie husband on TV.
