On Monday night, eager Married At First Sight fans tuned in to watch a brand new season of drama unfold, with the first two sets of complete strangers saying 'I do' in front of family and friends.
But all eyes weren't just on the nervous brides and grooms, particularly when it came to radio presenter Bryce Ruthven and workplace trainer Melissa's wedding.
A handful of eagle-eyed viewers couldn't help but notice a rather familiar face sitting in the audience on groom Bryce's side of the aisle.
Turns out, the man in the grey suit jacket is none other than former Big Brother star Jason Roses, who rose to fame in the 2014 season of the reality TV show.
Now a real estate agent and radio presenter, Jason also acted as emcee at Bryce and Melissa's nuptials and made sure to give his followers on Instagram an inside look at the couple's top-secret reception venue.
Posting to his Stories, Jason explained that he'd captured the behind-the-scenes footage of the table settings, other guests and even the journey to the location in a coach during filming back in September.
Once the episode finally went to air, however, he was allowed to let loose and share his pics and videos to his heart's content.
MAFS fans took to Instagram themselves to puzzle out who Jason actually was after spotting him in the background. Once one clued-in user revealed Jason's identity, several others breathed a sigh of relief.
"Thank you!!! My husband and I both said 'where do we know his [sic] from!!! haha," one wrote.
"I knew I recognised him," added another.
"OMG I thought he looked familiar," wrote a third.
Reality worlds collide
But how does a former Big Brother housemate know a MAFS star? It's a small reality TV world, it seems, with Jason and groom Bryce both working on the very same weekend breakfast radio show on Hit 104.7 in Canberra.
Bryce isn't the only Married At First Sight participant who moves in reality TV circles. Bride Bec Zemek has been linked to a number of famous faces including The Bachelor's Locky Gilbert and MAFS' very own Aleks Markovic.
In an Instagram post, Aleks gushed over Bec's wedding dress and revealed that the pair shared '14 years of friendship'.
