Married At First Sight groom Jayden Eynaud has hard launched his new romance with a mystery brunette, months after the pair were first spotted together in Queensland.

The former reality TV star, 27, shared sweet photos of the pair to his Instagram account on Saturday, but made sure not to share his new love’s name.

Keeping her identity secret, the professional Muaythai fighter posed for a sweet mirror selfie as he held his girlfriend’s hand.

The pair looked every inch the matching couple in their athletic outfits and white sneakers as they prepared to head out of the house.

Jayden and the woman were first spotted in January on a Gold Coast beach, and again days later as they strolled hand-in-hand in Sydney‘s Darling Harbour.

The couple were then seen enjoying an intimate dinner at an alfresco restaurant, before watching a firework display nearby.

Jayden appeared animated and relaxed, flashing his trademark grin as he engaged in conversation with his date.

The professional fighter kept his look sleek in an all-black ensemble, rocking a fitted button-up shirt, tailored trousers, and slip-on loafers.

Meanwhile, his new love interest turned heads in a figure-hugging white maxi dress that featured delicate spaghetti straps and a daring open back.

It appeared Jayden had found his happily ever after following his split from ex Eden Harper, who he was matched with on Married At First Sight last year.

The couple separated in April last year following a rocky relationship on season 11 of the reality dating show.

Eden confirmed their split on Instagram at the time after eight months of dating.

She revealed their relationship hadn’t translated off-screen as she hinted at some difficulties in the real world.

Later, Jayden released a similar statement, posting: ‘Sometimes in life, things don’t always go the way you had hoped for.

‘After the experiment, Eden and I went back to the Gold Coast and continued to enjoy living our lives together and getting to know each other every day.

‘However, unfortunately, our relationship ended not long before the end of the experiment airing.’

A source close to Eden told Daily Mail Australia the break-up came ‘completely out of the blue’ for her and she was ‘pretty shattered about it’.

‘Eden was in the dark about the whole thing and still doesn’t know how Jayden feels about her,’ they claimed.

‘Jayden didn’t really give her any real reason for breaking up with her.

‘She tried her best to try and get things to work out and fix whatever issues he had but he wasn’t willing to play game.

‘He just completely switched off one day and it wasn’t the same.’
