During an interview on radio network Hit FM with Fifi, Fev & Byron, the 31-year-old went into detail about what happened after the show between her and Michael.
"The one thing that bothered me is I never ever, ever cheated on my husband during the experiment and, I know he will be the first one back me up on that," said KC.
She continued: "It's so crazy him and I were talking about it yesterday and we were actually having a bit of a laugh and there are rumours and stories that are coming out that Michael and have hooked up in the experiment and all that stuff is just absolutely false."
"We always got along super well and yeah that's all I'm going to say about that."
"Have you hooked up after the experiment?" the radio host asked.
"You know everything is going to reveal itself after the experiment," KC replied.
"So that's a yes?" the host continue to ask.
"I'm not saying, I'm not saying," KC joked.
"So mark that down as a yes," said the host, before asking: "So what draws you to him?"
KC replied: "The thing I like about Michael is, he is just very honest. He's not sneaky, he's not shady. If he goes behind your back, he's gonna tell you".
This comes after leaked text messages between KC and Stacey emerged online, revealing that KC was asking for Stacey's approval before meeting up with Michael.
However, KC had already met up with Michael behind Stacey's back, as photos of the pair at a party in Sydney had come out.
"Last time I spoke to Michael he called me trash, a bad mother a piece of s**t. Told me he was going to ruin my life,' Stacey wrote to KC.
"Stacey I ran it by you to be respectful. I didn't go behind your back. I'm not going [sic] cause I don't want to hurt you and I don't want drama," KC insisted.
