"Hayley wasn't expecting to be confronted like that. I couldn't hear what they were saying, but Stacey was really upset over something," the onlooker continued.
"She was pointing at Hayley and getting really worked up as they argued with each other."
Earlier this week, Hayley’s ‘husband’ David Cannon spilled more details on her shock affair.
“We were sleeping in separate rooms by this stage,” the MAFS groom revealed to news.com.au’s Not Here To Make Friends podcast.
“I was in Tash and Amanda’s old room... And I heard this absolute howling out the front, it was Vanessa, she was absolutely hysterical. It came out (through Josh) that Hayley and Michael had basically been having dry sex on Chris and Vanessa’s bed.”
As we know, Vanessa Romito was in the room when Hayley and Stacey Hampton's groom Michael Goonan hooked up, telling New Idea that it was far worse than what viewers were led to believe.
“They were fooling around on the bed and dry humping. Shoes were flying everywhere,” she said last week, lifting the lid on the cheating scandal that took place while Stacey was spending time with her children in Adelaide.
"Michael walked into our room. He was really drunk and so was Hayley. Hayley said, ‘my husband (David) doesn’t want to f--k me’. And I said, ‘mine doesn’t either’.
[Michael] turned around and said, ‘I would f--k both of you’.”
Despite initially rejecting all involvement in the scandal while the cameras were rolling, Michael finally confirmed he'd kissed Hayley, however, insisted they were "just mucking around".
"We were all joking and having a laugh. We were mucking around with the phone and were like, 'Oh how funny would it be if this got out?'" he told TV Week of the naughty hookup.
"We were fully clothed, just being stupid, being loose, having fun, not really understanding the implications of what rumours can do to your life."
"We'd had a few drinks," he said, with Jonethen later revealing he was playing the 'Oh, I was too drunk to remember card'. "It got to the point where I was like, 'Did I kiss her? Didn't I kiss her?'"
