Married at First Sight 'groom' Billy Vincent had a tearful meltdown while breaking up with 'wife' Susie Bradley on-camera, last week.

And Susie, 25, burst into laughter while watching a clip of Billy's tantrum during an appearance on Today Extra on Monday.

The Brisbane nurse bonded with Today Extra's Sonia Kruger, who was equally amused by Billy's awkard display.

'I know I shouldn't laugh,' Sonia said between laughs.

'But it's just the way he delivers that, It's really funny Susie.'

Susie, who was also in fits of laughter, replied: 'Well, yes, it was and that was only a portion of it so that went on for quite some time... he got more aggressive at some times, other times he piped down and muddled his words a bit. It was full on.'

The clip showed Billy, 28, awkwardly confronting Susie and stammering his way through a bizarre rant during home stay week, at her home in Brisbane.

'Me and you are done, completely over and it makes me extremely extremely happy...' he said.

'I'm trying to help you, my dear, but you're a brat. You know, beauty is only skin deep... as well... some day you're not as.. gonna look as goo... good as you look now, my dear... and then what?' 

During Sunday's commitment ceremony, Billy and Susie both chose to leave the experiment.

Last week, part-time model, Billy, blasted the single mum as a 'hustler' and claimed she only went on MAFS 'to get on Instagram'.

'The girl's a straight up hustler. She cast for the show and said all the right things to all the right people to get onto the show so she could get on Instagram,' he told Fitzy and Wippa.

'She tricked everyone, me, my family - they thought she was sweet and bubbly then when it came to the show [she was like] 'nah I'm not up for this, I'm just here for the ride.'
