Married At First Sight's most talked-about stars turned up the heat off-screen on Sunday night, with more than a few eyebrows raised at Daily Mail's exclusive afterparty at Noir nightclub in Sydney.

Fresh from an emotional Daily Mail MAFS Final Dinner Party viewing at the Ovolo Hotel in Woolloomooloo, the cast wasted no time letting loose – and for some, that meant getting close to familiar faces who were not their TV spouses.

Joel Moses, 31, appeared to strike up a flirty connection with influencer Suzan Mutesi as the night wore on.

The sharply dressed groom was seen deep in conversation with Suzan, with the pair laughing, leaning in close and appearing completely absorbed in each other as the party buzzed.

At one point, onlookers noted the pair looked particularly cosy, fuelling speculation that sparks may have been flying well beyond friendly chatter.

Not far away, bride Julia Vogl, 35, was seen enjoying an intimate moment with MAFS 2025 star Ryan Donnelly.

The consultant looked striking in a bold pink mini dress that showed off her trim pins as she cheekily chatted with Ryan.

Witnesses say the pair shared playful banter throughout the evening, with Julia as giggling and whispering to the fellow reality star during their animated exchange.

The flirty encounters came after emotions ran high at the official Daily Mail MAFS Final Dinner Party, where the cast reunited to watch Sunday's dramatic episode.

The chaotic and endlessly entertaining reality TV stars dressed to impress as they stepped out at the Ovolo Hotel in Sydney for one last hurrah. 

Hotel guests were treated to a sea of busty displays and leggy ensembles, before the tears began to flow and madness ensued at the Palmer's sponsored event.

Alissa Fay was the frontrunner for best dressed, with the paediatric nurse, 33, opting for a daring look in a very low-cut halter-neck top.

She left little to the imagination in the cream, lacy cropped shirt, which almost bared her entire chest.

Pulling her curly blonde locks back into an updo, she finished her look with a matching slip maxi skirt.

The bride showed up on the arm of her new hunky beau, Ninja Warrior star Nathan Ryles, with the pair looking very loved up.

At one point in the evening, Alissa was spotted running her tongue over Nathan's shirtless torso while onlookers watched on in amusement. 

Alissa wasted no time moving on from her MAFS husband David Momoh after he dumped her at the altar during Final Vows. 

Meanwhile, fellow bride Rachel Gilmore flaunted her figure in a red-wine coloured corset dress by House of CB, while Bec Zacharia stunned in a backless dress and Stella Mickunaite put on an eye-popping display in a low-cut mini dress. 

Nine aired the first episode of the MAFS reunion on Sunday night.

They will come together again on Monday night to sit down with the experts one last time for a rehash of the highs and lows of the season.
