Married At First Sight's Bec Zacharia was spotted out and about after returning home to Adelaide following her heartbreaking Final Vows.

The controversial 35-year-old bride cut a sombre figure after being left 'blindsided' by groom Danny Hewitt, who dumped her during Tuesday's episode.

Dressed casually for her outing in grey bike shorts and a baggy white T-shirt, Bec treated herself to a takeaway lunch.

Wearing her long hair out, Bec completed her look with a pair of sandals and accessorised with gold hoop earrings, a chain necklace, a pendant and a set of bangles.

The outspoken reality star, wearing her eyewear in her collar, was seen taking a walk on Brighton Pier, one of Adelaide's famed tourist destinations.

At one point, for her day in the sun, Bec was seen leaning against a guardrail, lost in thought while she took in the view.

It comes after Bec Zacharia left the experiment this week with a heavy heart. 

Leading up to the big moment, Bec revealed that she was 'all in' on Danny, 34, admitting that she could not imagine her life without him.

'I am manifesting that it's going to be the best day ever,' Bec said as she made her way to the altar.

'I'm going to hear exactly what I hope to hear and we run off into the future together.'

Bec added that, despite the hurdles the couple faced during the experiment, her feelings for Danny had only grown.

'I love Danny. Even though we argue, that doesn't diminish the feelings I have for him,' she said.

'I can't imagine my life without him now.'

It was a sentiment that Bec shared in her final vows to Danny, telling her groom that he was her 'safe space.'

'Daniel, you're my best friend, my safe space, you make me a better person and you lift me up when I'm down. You're the kind of man everyone wants in their corner.'

'Today, standing here, I'm choosing you and I promise to choose you every day from here on out.'

While Bec was convinced she was walking away with Danny, he would soon break her heart with his brutal final vows.

Despite admitting that he had built a connection with Bec during the experiment, her constant involvement in drama proved to be too much.

Adding that the pair's time apart prior to Final Vows had given him clarity, Danny then delivered the final blow.

'As much as it breaks my heart to say this, I felt a weight come off my shoulders, at a time when I should've been missing you,' he said.

Clearly crushed by Danny's words, Bec offered an 'Okay,' as her voice shook and, despite Danny apologising, she added: 'I don't think there's anything more to say.' 

Inconsolable, Bec said that she had been 'blindsided' by Danny's rejection.

'I just didn't think it was going to go this way,' she said. 'I'm shocked.'

Bec then demanded her phone and an immediate flight back to Adelaide.

'Get me out of here, now!' she wept, as she fled the scene.
