They're one of the favourite couples to come out of Married At First Sight.

But now Belinda Vickers and Patrick Dwyer have been torn apart by the ongoing coronavirus pandemic.

In a post shared to Instagram, Patrick revealed that he and Belinda have been temporarily separated because she's in quarantine.

'Bel is currently in quarantine, so I can’t see her for a while. But here’s a short cute video of our time on MAFS,' he wrote, alongside a compilation of the couple together.

The personal trainer didn't specify why Belinda was in quarantine or if she had contracted Covid-19 or not. 

Fans were distraught by the news, with one writing: 'She’s lucky to have you. Quarantine as a single is the pits!'

'I thought you guys got married officially, why aren't you quarantining together?' asked another.

It comes just days after Belinda debuted her glamorous new celebrity makeover on social media.

The 29-year-old flaunted her new flame-coloured tresses - a departure from her signature brunette locks she wore on the show.

Belinda documented the dramatic makeover before she decided to share the results with her 72,000 Instagram followers.

'When you thought my hair couldn’t get any more extra,' she captioned the reel. 

Belinda's former castmates were quick to inundate her post with comments.

'Wow you really did mean orange haha I LOVE IT,' wrote Beck Zemek, while Alana Lister commented with a series of flame emojis. 

Belinda's dramatic makeover comes after it was revealed that she would be making the most of her 15 minutes of fame by signing on with talent agency THE.mgmt. 

'I love fashion and more importantly, I love to express myself through my clothes,' she told Daily Mail Australia. 

'Everyone should be allowed to have fun and wear what makes them happy.'

Since leaving Married At First Sight, Belinda's relationship with Patrick Dwyer has  gone from strength to strength.

They join the likes Martha Kalifatidis and Michael Brunelli and Jules Robinson and Cameron Merchant, other MAFS success stories.
