There's been no shortage of 'wife swapping' on this year's season of Married At First Sight. 

And on Monday, series star Billy Vincent revealed which groom he'd have switched spouses with if he were forced to. 

Speaking with HIT FM's Sam & Rach, the 28-year-old claimed he'd be best suited to brunette bride Tamara Joy, declaring: 'I'd have swapped with [her husband] Dan!' 

Billy said of Tamara: 'We were good friends, and she needs somebody that doesn't play up on her!' 

His comments appeared to be a swipe at Tamara's 'husband' Dan Webb, who has been seen getting flirtatious with co-star, Jessika Power. 

Meanwhile, Billy's own 'marriage' to Susie Bradley has come under considerable strain.

The blonde beauty left Billy close to tears during Sunday's commitment ceremony. 

During the episode, relationship expert Mel Schilling asked Billy what 'hurtful' things his wife had said to him during the week. 

'She's told me that she goes for bigger guys and I'm too small, that I have no balls, I'm strange and that I'm not a man,' he replied emotionally. 

'I know when someone is going out of their way to hurt me,' he added.  

Despite the rocky start to 'married' life, Billy chose to remain with Susie, saying:  'There's still that fire burning to try and make something work so I'm staying.'

Susie also chose to stay another week, adding: 'At the minute I'm going to stay. I can't leave after a week or I've wasted my time and Billy's'.
