On Sunday night's episode of MAFS Mike's relationship with TV wife Heidi Latcham broke down irreparably, with Heidi lamenting how her husband "has to be right all the time".
While experts convince them to carry on in the social experiment for another week, Woman's Day since reported that Mike and Heidi have split.
He is said to be dating Casey Stewart, the 26-year-old daughter of Gina Stewart better known as the World's Hottest Grandma.
