Married at First Sight Australia fans fumed “come on” as one bride made a shocking revelation on Monday (March 24).
Fans have eagerly been watching the 12th season of the hit matchmaking experiment, following its premiere on E4 earlier this month.
After last week’s explosive dinner party, tonight’s episode saw the couples attend the second commitment ceremony of the series.
Billy and Sierah were the final pair to grace the couch, with the couple admitting that they were intimate the previous night – but things have been quite awkward since then.
Things soon turned sour when Sierah admitted that she’s not keen to open up to her husband about her past, but she has spoken to co-star Adrian about her experiences.
Fans will recall that Sierah and Adrian began chatting at last week’s dinner party, after Adrian got into an argument with his wife Awhina.

They were seen laughing, with Awhina and Billy watching on suspiciously. However, they didn’t see their spouses playing footsie under the table.
Following today’s revelation, Billy shared his sadness that Sierah didn’t open up to him, with Awhina also feeling “blindsided” by the information.
“I’ve shared so much about my past with you and nobody else in the group. What I wrote in that letter in confessions week, I broke down that night. I broke down and revisited something I thought I put away and that was a lot for me, and you know it was,” Billy emotionally told his wife.
“So, that was a pretty big thing that I did, so the fact that it doesn’t feel reciprocated coming off that, but you can with something else is very, very strange and confusing to me.”
Awhina went on to share her frustration after learning that her husband had also been opening up to Sierah, especially after he refused to write a letter during confessions week.
Adrian tried to defend his actions by saying that he and Sierah felt more comfortable speaking without cameras, but expert Alessandra Rampolla wasn’t having any of it.

“I’m sorry, but that’s a cop out. The cameras are not there at night when you’re sleeping next to each other,” she said.
Concluding the chat, Alessandra then urged Sierah to share more about herself with Billy to help progress their struggling relationship.
MAFS viewers were also taken aback by the conversation, with many taking to X (formerly Twitter) to share their disapproval.
“So Sierah knew she didn’t like Billy and played footsie with Adrian. Disgusting,” one person wrote, with another adding: “Oh no, Billy was blindsided. This is terrible.”
A third fan said: “So you share your past with someone else’s husband then your own husband… come on!” with another similarly sharing: “Well this is very awkward.”
Addressing Adrian’s actions, a fifth viewer said: “Not Adrian opening up to Sierah and not his wife during the letter challenge!!! The audacity.”
