Married At First Sight star Belinda Vickers has announced her engagement to her 'border breacher' boyfriend Hayden Burbank.

The red-haired beauty, 31, and Burbank shared the joyful news on Thursday, telling the Herald Sun his unique Valentine's Day proposal included a treasure hunt at the Botanical Gardens.

'She's been phenomenal for me, the most beautiful, kind soul I've ever met. I had tears rolling down my face as I got down on one knee,' Hayden said.

Hayden added his public proposal caught the attention of the public, who burst into applause after Belinda said yes and accepted his dazzling engagement ring.

'It was always yes. It was 12 months after MAFS that we met and it really led me to him and opened up new people for me meet,' Belinda said.

The pair met in Melbourne through mutual friends in 2022. 

In 2021, Mr Burbank was jailed for three months after breaking Covid rules during the height of the pandemic.   

He hopped the border into the Northern Territory before travelling to Western Australia to watch Melbourne Demons win at Perth Stadium.

To dodge WA's strict border rules at the time, he falsified a rental agreement at a Darwin address while also fraudulently obtaining NT drivers' licences.

Burbank owns the trendy Morris Jones bar in Melbourne, which is a hotspot for reality stars and glamorous influencers. 

Their relationship blossomed after the bar owner spent 90 days behind bars at WA's maximum security Hakea prison, which earned him the jailhouse nickname of 'border breacher'.

Mr Burbank described his experience at one of Australia's toughest jails as 'the ultimate game of Survivor'.

'You have to form alliances and not do anything stupid and get through each day by day,' he told the Saturday Herald Sun in March 2022.

'They are the longest days of your life. I'm not built for jail. Nobody is built for jail.'

The Chapel St bar owner shared a cell with one of the prison's top dogs, a bikie, who would wake him up each morning and taunt: 'Border breacher, border breacher'.

Belinda found fame on season eight of Married At First Sight, which aired in 2021. 

She and her on-screen husband Patrick Dwyer were deemed the 'golden couple' of the series but split up after nine months.
