Married At First Sight's Scott McCristal breaks his silence on Gia Fleur's shock new romance

Married At First Sight's Scott McCristal has delivered a blistering takedown of bride Gia Fleur's shock new romance with Alan Wallace.

The emotional groom didn't hold back during Wednesday night's episode of Stan's MAFS: After the Dinner Party, accusing his TV wife of blindsiding him with what he sensationally labelled a 'coordinated and set-up' relationship.

'I was so invested in her, it was real, and I nurtured her, but I just copped so much sh*t,' Scott said.

The 33-year-old went on to address the bombshell photos of Gia with her new boyfriend, Love Triangle star Alan Wallace, which surfaced while their marriage is still playing out on screen.

Clearly blindsided, Scott labelled the images 'coordinated' and 'set-up', admitting he felt deeply disappointed after committing months of his life to the experiment.

'We put our lives on hold for three months,' he said, suggesting the situation had left him questioning everything. 

But it was his claims about what allegedly went on behind the scenes that painted the most explosive picture.

According to Scott, their relationship was 'much worse' off-camera, with the groom alleging Gia regularly threatened to walk away.

'I'll be very honest and upfront now that I can speak – off camera, you can only imagine,' he said.

'The ultimatums, constantly threatening to leave, and demanding that I say I love her.'

He further claimed Gia would 'go off for nothing' and accused her of focusing on everything but their relationship, even suggesting she sabotaged their bond.

'She would threaten to leave once a week,' he added.

Scott's emotional confession marks a stark contrast to what viewers have seen unfold on Married At First Sight, where Gia has been portrayed as trying to salvage the relationship.

For weeks, audiences have watched the bride, 36, attempt to keep her marriage alive despite ongoing tension and explosive arguments.

However, away from the cameras, a very different story has emerged.

Gia confirmed she has already moved on from the experiment – and is now in a serious relationship with Alan Wallace.

What began as a quiet connection has quickly escalated, with the pair now officially together and even discussing a future.

'The relationship began officially around New Year's Eve, but we were talking for a couple months off and on before then,' Gia explained.

Their first interaction actually took place toward the end of filming, when they crossed paths at a Sydney party after being introduced by Daily Mail Australia.

Despite only just meeting, Gia admitted she was instantly drawn to him.

'When I saw Alan for the first time I knew I liked him because I was getting super jealous of him speaking to another girl,' she confessed.

'I was instantly like that's my man – he just doesn't know it yet.'

Since then, the relationship has intensified rapidly, with Alan confirming the pair are now exclusive.

'It's very serious now,' he said.

'I've asked her to be my girlfriend and we're officially together.'

He added that the couple are already building a future together, revealing Gia is planning to move in.

Meanwhile, Gia has also taken aim at Scott, offering her own version of events surrounding their split.

'I knew my feelings for Scott were gone after the final dinner party when he treated me like a piece of shit,' she said.

She claimed their relationship deteriorated even further during the reunion and press commitments, alleging she felt disrespected and emotionally unsupported.

'I rarely felt complimented or reassured and I never really felt secure,' she said.

'I felt used.'

Gia also pointed to fundamental differences in their long-term goals, including conflicting views on having children.
