Married At First Sight's Bryce Ruthven and Melissa Rawson cradle their twin sons in the NICU after they were born prematurely at 10 weeks

Married At First Sight stars Bryce Ruthven and Melissa Rawson have been updating fans on their twin sons after they were born prematurely at 10 weeks last weekend.

On Sunday, Bryce took to his Instagram Stories to share footage of the engaged couple cradling the newborns while in the neonatal intensive care unit (NICU). 

Panning the camera over to Melissa, Bryce praised his fiancée for doing an 'incredible job' in calming down one of the boys. 

Dressed casually and seated inside the NICU, Bryce captioned the clip: 'I've got the calm boy today @lissrawson has the crying twin! 

'She's doing an incredible job though of calming him down.'  

The pair, who starred on this year's season of MAFS, welcomed their sons 10 weeks early last weekend. 

Bryce announced the news on Monday in a statement to New Idea, revealing that Melissa had given birth two days earlier.

'We had planned to spend the weekend building the nursery and setting things up for the twins, but that all changed early Saturday morning,' he said.

'Even though the boys have arrived early, they're doing really well and are getting the best care possible.' 

'The boys are going to spend a few weeks in NICU (Neonatal Intensive Care Unit). They're responding well to treatment and are squeezing our fingers which is the best feeling in the world,' he added. 

Bryce also posted a video on Instagram of Melissa in hospital preparing to give birth two days earlier.

Dressed in scrubs, a beaming Bryce said: 'Twin boys didn't want to stay inside and play. They wanted to come out and meet us in the real world.'

'I'm only 29 weeks, so they're very, very early. Fingers crossed everything is good,' Melissa added.

Melissa and Bryce, both 32, surprised fans in July when they announced they were expecting twins and engaged to be married.

In August, the couple announced via Instagram they were expecting two boys.
