'Meet our healthy twins': Married At First Sight's Bryce Ruthven shares images from fiancée Melissa Rawson's ultrasound

They stunned fans this week by dropping bombshell engagement and pregnancy news.

And Married At First Sight stars Bryce Ruthven and Melissa Rawson kept the reveals coming at a head-spinning pace on Wednesday, when they shared images of their twins.

Former radio host Ruthven, 32, took to his Instagram Stories to show his fiancée getting an ultrasound.

The video showed a masked Rawson, 32, lying on a hospital bed while getting the scan.

On the monitor was the unmistakeable image of two small figures.

Bryce captioned the post, 'Meet our healthy twins!' and added that he was 'so proud of how well [Melissa's] handling pregnant life'. 

Also on Tuesday, the couple revealed exciting new details about their upcoming nuptials on their podcast What Happens After... 

Bryce and Melissa - who revealed their children are due in December this year - also said they'd put their wedding planning on hold at least until after they welcomed their babies. 

'I think once the twins are born, then maybe we can start planning,' Melissa said of the wedding.

While they married in a farm barnyard on the Channel Nine show, the loved-up pair said their real union will be a little more low-key. 

'Our wedding on the show was a farm barn, so we can rule that out,' said 

'No not [a] huge [event] , I don't want to be inviting fifth and six cousins of distant relatives. I'd like to keep it close knit,' the bride-to-be said. 

When asked if any other MAFS stars would be invited to their big day, Bryce said: 'That's a no brainer – Jason [Engler] was on the list. 

And it appears not many more have made the cut, as Melissa chimed in saying: 'That's it!' 

However, the groom-to-be is still on the fence as he added: 'Maybe another couple… We'd consider.'   

The couple's union on Married At First Sight was a flashpoint of controversy this year.

Some viewers accused Bryce of 'domestic abuse' and gaslighting, but Melissa always maintained she didn't view their relationship as abusive.

A Change.org petition calling for Channel Nine to apologise for 'failing in its duty of care' towards Melissa gained thousands of signatures.

However, the campaign was dismissed by the network and show producers.
