The news comes at an awkward time for Mike, who was shown chastising his MAFS co-star Jessika Power for her affair with Dan Webb on Monday night's episode.
"Mike and Casey have been spending a lot of time together and she stays at his place on the Gold Coast a lot,” a source allegedly told an Australian publication.
“They’re planning to go public after the show, once Mike’s commitments finish.”
No word yet on whether Mike's met Casey's family, but we're sure he's had a glimpse of her mum's raunchy Instagram account.
At 47 (just three years Mike's senior), Gina has an incredible 142,000 Insty followers, a calendar and a number of "sexiest" and "hottest" titles under her belt.
So could Casey be the "kindred spirit" Mike's been searching the world for? According to his MAFS bio, she, "will be a confident and non-judgmental woman who appreciates his sensitive side and embraces his vulnerabilities."
We can't wait to see how this alleged romance and his marriage unfolds!
