Fans went wild for perfectly matched couple Jules Robinson and Cameron Merchant on the current season of Married At First Sight, and the majority of viewers believed theirs was a love that would last.
But a new teaser for Sunday night's episode hints at an explosive twist in the duos previously smooth sailing romance and threatens to derail the social experiment's most stable marriage.
The sensational footage dubs the upcoming installment "the most emotionally charged commitment ceremony ever" before flashing to former cricket pro Cam breaking down in tears.
WATCH: MAFS' Cam breaks down uncontrollably in new emotional preview - but does it mean he and Jules are over?
Seemingly caught off guard by her husbands hysterics, flame haired Jules wraps her arms round him asking: "Honey, what's wrong?"
Cam attempts to dry his eyes but can't conceal the pain etched across his face as the clip ends, leaving fans to wonder if their whirlwind relationship is doomed to failure after all.
MAFS enthusiasts were quick to praise Jules and Cam from the start of the season for their relatability and apparently genuine care for one another.
