A wild brawl erupted at the Married At First Sight reunion during Sunday night’s penultimate dinner party, well before the cast even finished their pre-dinner cocktails. 

Sierah Swepstone, 31, set the stage for a fiery confrontation, declaring just moments before her arrival that she returned to make war, not peace. 

‘I can’t wait to get to the party and tell everyone to get f**ked,’ Sierah said. 

‘Awhina Rutene is just an a***hole and tonight I am on a mission to drop her in the s**t in front of everyone. She is not going to be happy.’

The score Sierah intended to settle was her outrage at being called out for going to dinner with Awhina’s groom Adrian Araouzou behind her back.  

Sierah had previously branded her former friends ‘nasty c***s’, and also accused her ex-husband Billy Belcher and Awhina of conspiring to ruin her reputation.

The entire cast fell silent as Sierah made her grand entrance, with Billy saying he felt the room ‘go cold’. 

Sierah found a seat beside Adrian and gave him a cuddle, with Awhina perched on the other side of him. 

The simmering tension boiled over when Awhina confronted her on-screen groom  about the conspiratorial text exchange he had apparently shared with Sierah. 

‘Don’t talk about me when I am sitting here!’ Sierah snapped at Awhina, who retaliated, ‘You texted Adrian a bunch of things about me!’

Adrian looked quite pleased to have the two women shouting at each other literally over him. 

‘The way that you treated me! You paraded me in front of everyone!’ Sierah screeched, drawing the ire of fellow bride and Awhina’s closest friend, Jamie Marinos.

‘You were trying to f**k her husband!’ Jamie yelled, after Sierah pointed at the rest of the cast and told them to ‘be quiet!’. 

‘I think that Awhina is a horrible, nasty person. She has just proven me right. So I am going to drop her right in the s**t,’ Sierah later told producers, unveiling her dinner party plot. 

She then confronted Awhina, who had followed her out of the room, with Adrian close behind.

A shocked Adrian turned to Awhina and asked if she had made insulting remarks about him, repeated by Sierah, and she said 'some' of it was true

‘You said Adrian is stupid, he can’t spell, his business is a joke, that he’s too stupid to run a business!’ Sierah shouted.

A shocked Adrian turned to Awhina and asked if she had indeed made those remarks, prompting an embarrassed admission from Awhina that ‘some’ of it was true. 

‘Oh, Adrian will not cope with that,’ expert John Aitken noted. 

‘Do I seem like I’m dumb?’ Adrian asked the group, with the cameras cutting to the bemused reactions from multiple brides who were trying not to laugh. 

‘That is the worst thing you can say to me,’ Adrian fumed. ‘You don’t know nothing.’ 

A furious Sierah then stormed out of the room to collect herself. 

‘If this was the cocktail party… God save us all for the Dinner Party,’ Jamie quipped, after several other cast members also stormed out. 

Previously leaked screenshots of the text messages between Sierah and Adrian show her anxiously asking Adrian whether he’d told anyone about her attempt to convince the show’s producers to let her and Adrian return to the experiment together, as a couple.

Her big fear, she revealed, is that the plot would become a flashpoint at the reunion and she’d be verbally ‘attacked’ by the other participants.

 A production source told Daily Mail Australia the messages were ‘deeply concerning’ but not surprising given Sierah’s habit of ‘playing the victim one minute and then going on the attack behind the scenes’.

‘She was desperate to get back on the show and fix her image… now she’s burning bridges left, right and centre,’ they added.

The leaked texts come after it was revealed Sierah had been involved in secret meet-ups and flirtatious exchanges with Adrian, despite being married to Billy.

The controversy exploded at one of the dinner parties when footage captured Sierah and Adrian playing footsie under the table, an act that left both Billy and Adrian’s wife Awhina blindsided and humiliated.

The fallout was swift, with Billy choosing to leave the experiment after feeling betrayed by his wife.

Sierah tried to downplay the allegations, but the damage was done, and she ultimately decided to exit the show.

Married At First Sight’s dramatic finale will air 7.30pm on Monday on Channel Nine.
