Jason Engler and his 'wife' Alana Lister got into a heated argument during Monday's episode of Married At First Sight after she disclosed a private conversation they'd had with the other couples.

But it seems all was soon forgiven between the pair as they appeared to be getting along fine while shopping in Sydney during filming in October.

Jason, 35, and Alana, 30, were spotted arriving back to their hotel after visiting the local supermarket together.

Alana dressed casually for the outing in grey track pants and a matching coloured crop top.

The brunette beauty completed her ensemble with a pair of white sneakers and had sunglasses resting around your neck.

She styled her long locks in curls and appeared to be wearing a neutral palette of makeup for the outing.

Meanwhile, Jason wore comfortable black shorts and a white Chicago Bulls T-shirt.

He teamed the outfit with a pair of white sneakers, long striped socks and also wore a red hat.

Jason appeared to be in high spirits as he held a shopping bag in his hand while his 'wife' walked nearby.

Their outing comes after Jason was left reeling on Monday when Alana disclosed a private conversation they'd had with the rest of the show's couples.

She had told the other couples that Jason thought Bryce Ruthven's initial decision to 'leave' the experiment to protect his 'wife', Melissa Rawson, had been heroic.

Jason told Alana that he had told her that in confidence and he felt betrayed by her decision to divulge it to the rest of the group.

'In front of the whole group, you threw me under the bus, which was uncalled for, come out-of-the-blue,' Jason told her.

'My own wife, throwing me under the bus, I just feel like this is once again a situation where it proves that I can't trust you.'

'You don't have to agree with everything I say, but you don't have to throw me in front of the bus in front of everyone,' he continued.

Jason insisted that he was trying to 'stay out of the fight', after the other couples turned on Bryce, 31, and Alana had dragged him into the conversation.

'You think Bryce is a hero, but Bryce is in the wrong. I'm sorry, Bryce is in the wrong and I'm never going to have his back,' Alana told him.

But Jason insisted their argument wasn't about Bryce, as Alana grew teary.

'Okay, this right here is why this will never work,' he told a stunned Alana, speaking about their own relationship.

He later added: 'I don't care that you're not on my side about Bryce, but it hurts that Alana's broken my trust. It won't work... I don't trust Alana.'
