"Mikey looks like my son, there's no way," Stacey told the radio hosts after refusing to join Michael on air.
"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.
"So Mikey reached out to me and asked to get coffee because he wanted to tell me what Michael was saying about me all night. It was nothing more than that," she insisted.
This isn’t the first time Stacey has spoken publicly about her ‘supposed affair,’ echoing a similar sentiment in a recent interview with New Idea.
"Nothing happened between Mikey Pembroke and I. No sexual relations. Nothing. I can guarantee that. And I can sit here and swear on anything.”
“I understand where the rumours came from. We did share coffee and we did hang out. I swear that Mikey and I have never shared any sexual intimacy."

Spreading a different narrative, groom Mikey, who was originally paired with finance analyst, Natasha Spencer, confirmed in an interview with News.com.au that they slept together.
“I can confirm we did have sex, but it was clearly after Natasha and I had agreed with producers that our relationship was over, and Natasha knew we weren’t together,” Mikey said.
“I actually didn’t want this (story) out as it’s not the best way to end my time on the show, but it did happen.”
