While producers of the Nine show have yet to confirm the rumours, speculation is mounting as to what exactly could have caused the break in filming.
“There is heaps more partner swapping in this season,” Nick continued.
“Apparently, they've needed to check someone in [to a rehab facility] because they've gone so loose on the show that they were worried about their mental wellbeing,”
According to the Hit106.9 host, the unnamed cast member’s break down may have been brought on after the couples spent their first night together after the ceremony.
“It's a girl that is trying to consummate the relationship with her new husband - and he's not into it, on the first night he's just like '’oh we haven't been together for that long'’”, he said.
“But she's pretty bloody keen - like yelling ‘f**k me, f**k me,’ over and over and over again,’” the host said.
In a statement to Daily Mail Australia, Nine producers remained tight-lipped.
“As always with Married at First Sight, the rumour mill is in overdrive. All we can say is: tune in to Nine early next year,” they said.
