MAFS Australia’s Billy left shell-shocked as tearful bride Sierah reveals secret connection to another groom

MARRIED At First Sight Australia fans were left open-mouthed as Sierah confirmed she had been talking to Adrian behind husband Billy's back.

At the end of Thursday night's episode –Sierah andAdrian appeared to be discreetly playing footsie under the table.

And tonight, Sierah gave Billy the cold shoulder after they got intimate for the first time since their honeymoon.

Earlier in the episode, Billy admitted he could feel the “awkwardness” from Sierah the next morning, but couldn't put his finger on why.

On tonight's commitment ceremony, things came to a head when Sierah dropped a huge bombshell.

While discussing the lack of connection she felt for Billy, Sierah revealed that she ended up confiding in Adrian off screen.

Billy felt betrayed because he had opened up to Sierah with an emotional letter about feeling rejected by his father, while she chose to open up to someone else.

Adrian also confirmed that he opened up to Sierah, leaving his wife totally confused that he would share his past with another bride.

During their chat with the experts, Sierah admitted she wanted more “physical touch”, while Billy wanted an emotional bond.

Discussing her and Billy's night of intimacy, she said: “It felt like a drunken fumble.

“I like Billy but I feel my feelings are fleeting.”

But Billy admitted: “I felt like we were connecting.”

After finding out that Sierah had confided in Adrian, Billy was left hurt.

Sierah told the experts: “I don't want Billy to think I'm damaged goods,” as she broke down in tears.

Awhina admitted she was left hurt by Adrian for his behaviour lately – with him often “shutting her down” leaving her “without a voice”.

She told him on the sofa that she didn't feel they were “compatible” after he constantly fails to validate her.

On last week's Dinner Party, Sierah, who is married to Billy Belcher, was sat beside Adrian, who is married to Awhina Rutene.

After Adrian and Awhina had a row at the dinner table over how she has a child but feels he is reluctant to accept that she is a mother, Adrian turned his attention to another wife.

Following Adrian and Awhina's quarrel, he could be seen smirking after speaking to Sierah, who had leaned in for a chat.

Sierah then moved her foot towards Adrian's foot, with them playing footsie in a discreet way beneath the table where everyone was eating dinner.

Adrian quickly covered his face with his hand, seemingly rather flustered by their physical exchange.

Meanwhile, Sierah smiled before pouting in a kissy way, almost blowing a kiss towards Adrian as a way of flirting.

This followed on from Confessions Week, when both Adrian and Sierah refused to open up to their partners about their lives.
