The Adelaide dad's not so subtle swipe at the law graduate comes after their co-star, Drew Brauer, said she flew off the handle when she discovered he'd moved on with fellow bride KC Osborne.
"Stacey blew up for obvious reasons," the 32-year-old singer told Hit103.5 breakfast show hosts Carly and Seamus. "They had been together and there was obviously still feelings there. She was quite upset about it. That was the start of some stuff."
Fans of the couple know they've been flaunting their relationship left, right, and centre, with Michael recently revealing he's even introduced KC to his son, Connor.
Taking to Instagram to answer people's burning questions about their unexpected romance and life after MAFS, the high flying party boy said she absolutely adores his toddler— who he shares with his ex-girlfriend.
"I have met little Connor, his son. He's adorable. It was fun to babysit, that's for sure," the professional dancer said with a smile before Michael joked, "He actually babysat her for a few hours and he's nearly three."
Despite being an open book, Michael has remained relatively coy about his son, revealing last week that he prefers to keep some aspects of his life private.
"I don't talk about him often— my son's name is Connor. I've kept him well away from all of this nonsense," he said during another Instagram Q&A. "He's an absolute gorgeous boy. He will be nearly be three soon and I love him with all of my heart."
Since KC and Michael went public with their relationship earlier this month, it has been plagued by rumours she's dating the millionaire for his family's fortune.
Sadly, the constant backlash has led her to address this horrible allegation more than once, admitting it's not only hurtful but couldn't be further from the truth.
"People have been calling me a gold digger, I'm just with Michael for his money, all this stuff," the 31-year-old said while chatting to KIIS FM's Kyle Sandilands and Jackie 'O' Henderson via Zoom.
