While they've never been fond of each other, Hayley said the way Stacey acted when she hooked up with her television husband has only made getting revenge even sweeter.
"The whole time [Stacey] was like, 'I am the victim here, I'm the victim!' The only thing she's the victim of is pointing the f**king finger. What a dog. I only ever kissed Michael and I'm ready to say it exactly how I see it."
This isn't the first time the bodybuilder has spilled on the second affair to rock the experiment, revealing last week that Stacey's trying to bury the scandal because she's embarrassed by her actions and is fearful of looking like a hypocrite.
"Stacey and someone else are pretty much trying to bring Mikey down at the moment and say that, you know, he's a terrible person, that he's got a bad character, that he's making all this stuff up to stay in the spotlight and to totally defame Stacey," she said last week.
"It's utter bullsh*t. Stacey just can't stand on her own two feet and cop it on the chin and I'm pretty sure that Mikey's going to do a lie detector test to prove that he did get a leg over Stacey," she added, hinting the truth will be exposed at the upcoming reunion episode.
As per both Hayley and her ex-husband David Cannon, we're set to see Michael and Stacey's relationship implode at the final reunion after he's confronted with shock details about what went down behind the scenes. The mum-of-two has since confirmed they parted ways and cut ties immediately after filming had wrapped.
"You will see at the reunion that he thinks I cheated on him. Uh, Mikey comes back for 20 seconds of fame instead of 10, so that's pretty much it," Stacey said on Instagram.
"Mikey looks like my son, there's no way," Stacey said in February. "He is not my type. What happened was I was in Adelaide when he hooked up with Hayley and no one told me what was going on and I was all alone."
