The 44-year-old podcast host took to Instagram to share his big news.
Posting a photo, Mike Gunner left very little to the imagination.
Posing for the camera, the MAFS star was stripped down naked, laying on a bed with just a blanket covering his modesty.
He confirmed to fans about his modelling, writing: "Photo shoot for @pillowtalkbyminx_ @gilttripempire."
Ex Married At First Sight co-star Nic Jovanovic decided to comment on his friend's big move, penning, "😂😂😂😂😂😂."
Mike, who off the back off his Married At First Sight fame launched the podcast Stick To Your Knitting, spoke about how he'd happily picks up hitchhikers.
He then forwarded his views onto his his two female co-hosts Bella Frizza and girlfriend Jessi Williamson - confused as to why they wouldn't do the same.
"I picked up a hitchhiker. Have you ever picked up a hitchhiker, Bella?"
When Bella told him that she didn't want to "get murdered", MAFS Mike replied, "As a man, I don't fear it."
MAFS MIKE'S "MAN" COMMENT WOULD PROBABLY ANNOY A LOT OF PEOPLE INCLUDING CYRELL AFTER SHE WAS THE VICTIM OF A HORRIBLE ATTACK. WATCH THE SHOCK ASSAULT, WHICH WAS RECORDED.
The electrician tried to convince the ladies that picking up a hitchhiker was totally safe, by referring to the film Thelma and Louise.
"If you were with a girlfriend? Think Thelma and Louise... there's a guy on the side of the road with a cowboy hat... so a Brad Pitt-like guy is standing on the side of the road, he's got the shirt off, a little bit of sweat on the chest, the tight jeans - what, are you just going to drive past him?"
