Married At First Sight’s most controversial friendship appears to be thriving off camera.

Brides Gia Fleur and Juliette Chae were spotted enjoying a secret lunch together in Sydney, after filming the retreat, defying producers’ strict new rules that were introduced after a chaotic night out earlier this season.

The pair looked thick as thieves as they strolled through the city hand in hand following the catch-up.

They were joined by former brides Rebecca Zukowski and Melissa Akbay who had already been booted from the experiment.

The cheeky reunion comes after producers introduced strict curfews and drug testing following a wild night out at Bondi hotspot Icebergs that insiders say completely derailed filming.

In exclusive photos taken by Daily Mail, Gia turned heads in a figure-hugging chocolate mini dress layered under an oversized beige blazer.

The blonde bride completed the glamorous look with nude heels, oversized sunglasses and a tiny handbag as her long hair fell in loose waves.

Walking beside her was Juliette, who opted for a more relaxed look in a sleeveless denim mini dress with a front zip and black flats.

The brunette wore her curly hair loose and shielded her eyes behind dark sunglasses while carrying a small bag and drink as the pair chatted animatedly.

At one point, the two women clasped hands while walking down the street, clearly enjoying their day out.

Their close bond has become one of the most talked-about ‘friendships’ of the season.

Viewers first noticed the pair growing close during the couples retreat, where they quickly formed an alliance as tensions between the brides escalated.

The duo became inseparable during the dramatic getaway, often backing each other during heated confrontations.

Their friendship was particularly evident during the explosive clash involving fellow bride Bec, where the pair confronted her during a tense showdown.

During the confrontation, Juliette delivered one of the most brutal lines of the season.

‘You’re the dumbest c*** here,’ she fired during the heated exchange.

Gia remained firmly by her side throughout the confrontation, backing her friend as the argument spiralled in front of the rest of the group.

The moment cemented their reputation as one of the experiment’s most formidable alliances.

But while the pair presented a united front during much of the retreat drama, cracks began to emerge as the experiment continued.

During a later dinner party confrontation, Juliette appeared to expect Gia to jump in and defend her during an argument with other cast members.

Instead, Gia remained noticeably quiet, leaving Juliette to fight the battle alone in front of the group.

The awkward moment left some viewers questioning just how strong their friendship really was.
