Confirmation Michael deceived her on more than one occasion comes after KC reached out to Stacey to ask if she'd approved of her grabbing a drink with the successful businessman while he was in Sydney.
"I spoke to Michael a couple [of] days ago he asked how I was we had a chat. He said he was coming to Sydney and if I wanted to go meet him for a drink," KC told Stacey in texts obtained by Daily Mail Australia. "I said if I do I would first [ask you]... Not sure I will but I do see Michael as a friend but that's it xx."
"WTF r u srs?" Stacey responded.
Shocked by her candidness, Stacey proceeded to lash out at her former friend, claiming Michael called her "trash" and said, "he was going to ruin my life".
"He can have a drink with you but not even apologise to me or reach out," she wrote. "He's a piece of s**t. It's your prerogative but he has motives."
After urging her to think twice about the implications of being seen with the party boy, she backed down and agreed not to grab a drink with him.

"I thought u would know obviously I have nothing to hide if I straight up asked ou. I didn't go have a drink and then tell you. I told you beforehand. I have never heard you trash him once. That's why I said he wouldn't cause he knows better and knows I would stick up for you anyway," KC wrote. "I'm not going [to meet Michael]. Not worth it. Don't want to upset anyone. Have a good night.'
The only problem is KC was lying all along! The text messages were exchanged on February 25, exactly 10 days after the paparazzi photographed her arriving at a house party with Michael where they were reportedly spotted getting cozy.
While this is the second cheating scandal Michael has been involved in, the controversial groom revealed before the intruders entered that he's still with "someone" from the show— meaning he's definitely still hooking up with KC!
"I really only chat to one person on the show who is amazing. I can't give away all of my secrets but I can 100 per cent confirm that I am seeing someone from the show."
