Married At First Sight has featured its fair share of conflict this season.

And a new feud will reportedly emerge during the show's upcoming reunion, as two participants go head to head during a girls' night out.

According to New Idea, Booka Nile will face off with Belinda Vickers after a 'difficult conversation' about their respective husbands' involvement in her marriage breakdown.

Booka was reportedly left 'fuming' following a discussion about the infamous letter from Belinda's husband Patrick Dwyer that led to Booka's split with Brett Helling. 

The showdown was so emotionally charged that bride Joanne Todd left the girls' night in floods of tears, New Idea claims.

Booka clashed with Patrick during 'feedback week' on MAFS after he wrote a letter accusing her of being 'self absorbed' and acting selfishly throughout her marriage to Brett - who at the time was his close friend. 

Belinda had no involvement in the content of the letter, except for acting as a scribe.

While Brett insisted he only had good intentions, the letter backfired spectacularly and led to Booka accusing Brett of speaking poorly about her behind her back.

The bombshell letter led to the implosion of Booka and Bryce's marriage, culminating in the couple opting to leave the experiment during Monday's final commitment ceremony.

Speaking to Daily Mail Australia on Tuesday, a close friend of Booka's has rubbished the claims.

'It's 100 per cent not true,' they said. The source continued: 'Booka actually quite likes Pat and Bel and they went out a few nights before and had a whale of a time.'

'There were never any negative feelings or anger towards him after the letter.'

Meanwhile, heavy metal musician Booka has released an entire album of songs inspired by her experience on Married At First Sight.

In a song titled 'Patrick', Booka sings: 'Thank you Patrick, for being a dog. Thank you Patrick, for stirring the pot.' 

'I've always plagued by feeling of inadequacy. But from what your saying I suffer grandiosity. It's nice to see that Brett has found a friend he can trust. Go on right ahead and throw him under the bus.'

She continues: 'You have gone and helped me see what my husband truly thinks of me. It feels nice to finally see clearly. So thank you for setting me free.'
