Martha Kalifatidis and Michael Brunelli found great success on Married At First Sight in 2019, but Martha's popularity and hectic schedule could be creating tension for the once tight-knit pair.
Not too long ago, the 32-year-old beauty influencer admitted, "My work-life balance isn't the healthiest right now. But funnily enough, I thrive living like this."
While Martha says Michael, 30, supported her going on Celebrity Apprentice, it has caused problems.
"He said that while I was filming, it was like he was a single lonely guy again," Martha admits.
"Our relationship was on pause... I'd literally be at home long enough to sleep and that was it."
Indeed, Martha and Michael seemed to have a heated talk at Sydney's Bondi Beach recently.
The alleged rift comes after the pair have defied the odds and come out as one of the most successful couples to ever meet on the MAFS franchise.
However, they're not without their very public, and often hilarious, 'stoushes'.
In May 2021, Michael shared a hilarious Instagram reel where he pranked Martha into thinking he'd shaved off his facial hair.
A horrified Martha wrote a number of flurried, concerned messages back to his Photo-Shopped image where a clean shaven (and very different-looking) Michael beams at the camera.
"This better be a joke," was the crux of her messages.
Martha later commented on his video: "Voldemort has seen better days than you clean shaven... just saying."
