Hayley has since responded to his deeply serious accusations, telling New Idea that any suggestion she has an ongoing drug problem is completely false and insists she has tests results to prove it.
"There’s been an article come out where David says I might not be as clean as what I’m saying," said the furious finance broker who has been open about her debilitating, decade long drug dependency.
"He can say whatever the f*** he wants... but the absolute truth is, I was blood tested halfway between the filming and before I got on the filming. For a period of eight-to-nine weeks, I was getting drug tested."
Due to her challenging past, Hayey told the outlet the show's executive producer kept a close eye on her throughout the experiment and ensured there were strategies in place in the event of an emergency,
"I got drug tested on the show. I had to do a pee test, I had to do a full blood test – the duty of care was always above and beyond. Do you want me to send the stick I peed on?
"Still to this day I’m seeing the show’s physiatrist and making sure I’m seeing my mentors and the fact that David is clutching at straws to say something so awful."
David made it clear from the get-go that he can't stand the woman the MAFS experts paired him with, claiming we will see her true colours in the near future.
"She keeps a fairly nice face in front of the camera for the most part. But finally, we got to see the ugly side of her on camera and it's not just me being crazy thinking she's one thing behind closed doors and another thing on camera."
"I wouldn't buy the drink at a bar, let alone marry her," he concluded. "I know she is a horrendous human being and there's nothing she could say to me to change my mind."
During the insane takedown video, David also slammed the MAFS experts for their bizarre pairing, claiming John Aiken, Mel Schilling and Trisha Stratford "don't know f***ing sh*t".
It's all fake and it's so hard to trust them when they've mismatched me so poorly," the controversial reality TV said. "They couldn't even organise a f***ing root in a brothel.
"I am looking forward to taking them to task when I see them. They matched me with a drug addict, f***ing smoker who's tall. Who the f**k do they think they are? It's bizarre they could actually think that was a person I would fall in love with."
