Two more "marriages" bite the dust as the fallout over poo-gate continues. Catch up on Married At First Sight in minutes with this recap!

This season of Married At First Sight has already featured multiple cheating scandals, a poo toothbrush scandal and the first couple to be kicked off the show – but the most wild rumour about the show has only just emerged.

According to this week’s edition of New Idea, Mikey Pembroke, 28, has been left reeling after discovering Natasha Spencer, 26 – whom he was “married” to on the show before their exit last night – had sex with his dad after filming ended.

The Sydney-based operations manager addressed the bonkers story on Nova’s Fitzy and Wippa show this morning, admitting the story had come up during filming of the reunion episode in January but denying that it was true.

“It’s not true – it’s ridiculous,” he told the hosts, claiming that the headline was generated by MAFS love rivals-turned-friends Natasha and Stacey Hampton.

“Stacey and Natasha, now they’re best friends, but they weren’t friends during the show. This is peak season for throwing people under the bus, and obviously they’ve come together and it looks like they’ve come up with this story (for the magazine).”

Mikey explained that his dad, who is a doctor, was furious about being dragged into the scandals surrounding the controversial show.

“I know for 100 per cent certainty that he would never and has never slept with Natasha or texted her or done anything like that,” he said.

“He’s not happy about it, he’s like, ‘Why am I getting thrown into this stuff?’ He didn’t want me to go on the show on the first place. He’d never do something like that (sleep with Natasha), it’s so far-fetched – they’d never even caught up outside the show.”

During the interview, Mikey explained that the accusation had been hurled at Natasha by Stacey during the reunion, although he admitted he didn’t know if the conversation would make it into the final edit.

“At the reunion, Stacey and Natasha go nuts about that something that happens, and then Stacey goes, ‘Well, you slept with Mikey’s dad’ – and then turns around and says I told her that,” he said.

“There’s a few stories around about Natasha and stuff, so I don’t know if it’s come from that – the only time (Dad) would have socialised with Natasha is on the show, when you meet with the parents and have a one-on-one.”

Natasha has since responded to the explosive rumour, claiming it is false.

“The accusation that I slept with Mikey’s dad is completely untrue,” she said in a statement to news.com.au.

“I cannot believe that anyone would start such a horrible rumour. The only times I’ve met Mr Pembroke was on the show during the wedding and on parents day.”

She went on to urge people to “stop spreading this vile and inappropriate gossip.”

“It’s not fair to bring Mikey’s family members into these unfounded stories.”

Both Mikey and Natasha came head-to-head over at the Kyle and Jackie O show on KIIS this morning, where Mikey admitted the wild stories emerging from this season largely happened during the controversial filming shutdown.

“It was a crazy time in the experiment, there were parties going on, things got out of control – they had to shut down shooting for a week just to work out all the storylines and what happened (after cameras stopped rolling),” he explained.

“There was a lot of weird stuff going on, for sure. I think that’s why the show was so upset, because they missed so much stuff. They were livid because it’s really hard to tell the story unless they get it on camera.”

While Mikey and Natasha decided to exit the series in what appeared to be a very amicable way last night, it was a very different story when they reunited for a very uncomfortable showdown on the radio show this morning.

“We’re not really (fine), there’s a lot of stuff that’s come out that we don’t need to go into detail with,” a clearly upset Natasha told Kyle and Jackie O.

Later in the segment, Stacey called in to the show to again deny Mikey’s claims that they slept together, with the three MAFS contestants quickly launching into a furious, messy argument.

“Everyone’s talking at the same time, that’s no good,” Kyle interjected at one stage – but it didn’t take long for the group interview to again descend into chaos, with Mikey and Stacey attacking each other over who was telling the truth and who was lying about their alleged hook-up.

The latest scandalous headlines come after a he-said, she-said battle erupted last week between Mikey and Stacey – who was matched with Michael Goonan on the show – over reports they had a secret liaison.

“I can confirm we did have sex, but it was clearly after Natasha and I had agreed with producers that our relationship was over, and Natasha knew we weren’t together,” Mikey told news.com.au.

“I actually didn’t want this (story) out as it’s not the best way to end my time on the show, but it did happen.”

Mikey’s comments follow a statement given by Stacey to Woman’s Day last Monday, in which she flatly denied anything had happened between them after they published leaked texts between the pair hinting at a secret relationship.
