Married At First Sight's Jack Dunkley and Tori Adams have been spotted partying with some of the show's most talked about grooms.

In a series of snaps shared to Bryce Ruthven's Instagram on Sunday, Jack and Tori are all smiles as they pose alongside Jason Engler, Dan Hunjas, and Daniel Holmes.

The friendly photos, which appear to have been taken at a casual get-together for Bryce's birthday, have sent MAFS fans into a tailspin, with many wondering about the nature of their relationship with these controversial figures. 

The first image captures the group in a moment of fun, with Jason and Jack hoisting up Tori's leg in a jovial display of camaraderie.

The laid-back vibe is palpable, with beer bottles and wine glasses adorning the kitchen island, hinting at a night of light-hearted fun.

A second photo shows the men standing together, again exuding a strong sense of unity.

Jack stands prominently among them, further cementing his and Tori's association with the grooms who have been the subjects of much debate in past seasons.

These photos have certainly set tongues wagging, with some fans expressing their surprise and disappointment at Jack and Tori's newfound affiliation.

'Omgff gross so many things wrong w this pic,' one fan wrote.
