While Fox FM producers are said to have given the bodybuilder the letter, Stacey is 100 per cent sure she forged the note in an attempt to either humiliate her or create even more drama.
"This is fake, sorry. I know his writing," Stacey commented below the Instagram post. "That's not fair at all, Hayley. You can't forge someone's confession... he is dyslexic. I don't even think much of him right now, but this is weirdly desperate and low."
After noticing her brutal comment Hayley hit back, writing: "How desperate, Stacey, saying I forged [Michael's] confession letter... you are a terrible supposed lawyer. I thought you didn't argue with fact? You best shut up and get your facts right before you point the finger again," she savagely wrote.
After dozens of viewers weighed in on the drama, with many taking Stacey's side, Hayley said she plans to prove she was being honest.
"For anyone that cares, I contacted the radio station this was on and they're calling me back in five minutes. I’m also sending them what Stacey wrote/ THIS IS FAKE IM SO...."
As we know, Michael has been embroiled in a cheating scandal with Hayley for some time now. And while Michael is adamant they never hooked up, there's far more to the story. Appearing on A Current Affair on Thursday evening, the reality TV bride confirmed she hooked up with the entrepreneur multiple times during their boozy night out, insisting he's denying the cheating scandal because he's embarrassed he "hooked up with a bogan".
"It wasn’t just one kiss," the 32-year-old said. "It wasn’t this big in-depth thing. I walked into a room. He had his Tommy Hilfiger top on walking around like the alpha male that he thinks he is. And we macked on," she continued.
Starring on Talking Married hours before, the finance broker slammed Michael for refusing to claim responsibility for his part in the scandal, claiming his excuse that he was "too drunk to remember doing it" is nonsense.
"Was it cheating? I kissed someone! That's cheating. Oh, hang on, let me answer it how Michael would."
Doing her best impression of the dad-of-one, Hayley said: '"Um... so I did flirtatious behaviour and I got a lap dance off Hayley, but if you call that cheating, then I have cheated..."'
