But it sounds like we might have to wait until the reunion episode for all the juicy details.
Appearing on radio Monday morning, KC was grilled about the rumours, and her caginess spoke volumes of their validity.
The speculation comes after Stacey Hampton – Michael’s “wife”, said she feels betrayed by her former friend.

While whispers the two cheated on their spouses while MAFS was filming have been rife, KC instead hinted a romantic connection was only struck up once the show wrapped.
Speaking on Hit 101.9’s Fifi, Bev and Byron, KC was quick to clarify she never actually cheated on “husband” Drew Brauer.
“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,” she said, adding of Michael: “We always got along super well and yeah that’s all I’m going to say about that.”

She was then asked if her and Michael hooked up after the experiment, to which she answered: “You know everything is going to reveal itself after the experiment.”
When probed if that was “a yes”, she responded: “I’m not saying, I’m not saying.”
And when asked what she liked about Michael Goonan – this year’s most controversial contestant, she said: “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”.
Earlier in the season, Michael and fellow former contestant Hayley Vernon were locked in a fiery he-said, she-said at one of the group dinner parties, with Hayley claiming they had a “party pash” while Stacey was visiting her children in Adelaide.
Stacey levelled her fury at Hayley over her party-boy match, opting to forgive him immediately and doubting the kiss ever happened.
Since the whispers Michael and KC hooked up began last week, Stacey has told The Daily Mail: “KC was my friend. She went behind my back and proceeded to see Michael after he broke my heart. KC and I are now no longer friends.”
