A set of cheeky ‘bathroom confessions’ filmed at Daily Mail’s Married At First Sight Final Dinner Party has lifted the lid on explosive off-camera secrets — including a shock hook-up and a surprising admission about a hidden romance.

During the candid video series filmed in the bathrooms at the Ovolo Hotel in Woolloomooloo on Sunday, the MAFS stars didn’t hold back as they shared their most unfiltered thoughts.

In one standout moment, bride Rebecca Zukowski, 51, made a bold claim about fellow contestant Bec Zacharia, stating that she had been intimate with a fellow groom – who was not her husband Danny Hewitt.

‘A bride and a groom who were not matched played tongue hockey. Do you want to know who it is? Bec and Farmer Luke [Fourniotis],’ Rebecca cheekily claimed. 

According to sources, the hook-up occurred at Gia Fleur’s birthday bash earlier this year. 

Elsewhere, fellow bride Alissa Fay confirmed she hid her relationship with Australian Ninja Warrior star Nathan Ryles for months – after previously denying their romance.

‘I may or may not have hidden my relationship… and lied to everyone,’ Alissa admitted, as she cuddled up to Nathan.

‘The mirror in our bedroom has seen some things!’ Nathan added.

Alissa wasted no time moving on from her shock split with David Momoh – and before Sunday night’s Daily Mail party stepped out for a cosy date night with Nathan.

Nathan shared a loved-up photo taken at Sydney eatery Bill & Toni’s to Instagram of him and Alissa alongside fellow bride Bec Zacharia.

Alissa looked radiant in a sleeveless olive-toned zip-front top, wearing her blonde hair in soft waves and opting for a bronzed, glowing make-up look. She beamed at the camera, appearing relaxed and happy.

Meanwhile, Nathan kept things casual in a white T-shirt layered under an open button-up shirt, flashing a wide grin as he leaned in between the two women.

The caption over the image read: ‘Might need some earplugs’ – hinting at a lively night out between the group.

Alissa’s relationship with on-screen husband David dramatically imploded at Final Vows, where he blindsided her by ending things despite earlier declarations of love.

The new couple attended the Daily Mail MAFS Final Dinner Party on Sunday night in Sydney

Behind the scenes, their relationship had been plagued by tension and trust issues, with David later admitting he had considered leaving earlier in the experiment. 

But while viewers are only just watching the heartbreak unfold, Alissa has already well and truly moved on.

Daily Mail revealed she struck up a romance with Adelaide-based personal trainer and Australian Ninja Warrior star Nathan shortly after filming wrapped late last year.

The pair had known each other for years before reconnecting, with their relationship quickly escalating into something serious.

Alissa is ‘besotted’ with Nathan and the couple are already living together and exchanging ‘I love you’ just months into their romance.

Nathan has also publicly gushed over their connection, saying they bring out the best in each other.
