“Hayley, you’re not the only one I kissed! Plenty more secrets,” the letter read, signing off with "M".
It stems from the fact that Michael and Hayley shared a kiss while on the show, to which Michael has vehemently been denying ever happened. While Stacey isn't with Michael anymore and is furious with how he handled their relationship on the show, she is taking his side in this one.
"This is fake, sorry. I know his writing," Stacey commented on 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."
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."
Many people took Stacey's side in the matter, forcing Hayeley to get the #receipts.
"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...."
While it seemed like Michael was initially denying the kiss ever happened to protect his marriage with Stacey, Hayley thinks he has other reasons.
Appearing on A Current Affair on Thursday night, the reality TV bride confirmed she hooked up with Michael multiple times, but says 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.
