He's a model and aspiring actor, whose portfolio includes a 2012 McDonald's advert and starring on Married at First Sight.

So it's no surprise that Billy Vincent takes pride in maintaining his physical appearance.

The 28-year-old told Woman's Day on Monday that like many stars, he has used Botox on his forehead.

'I don't mind that the Botox stopped me frowning so much,' he said, adding that he got the treatment to prevent sweating.

'I wish I had it for the show, because all I do on TV is scrunch up my face with disbelief that people like this exist.' 

The personal trainer isn't alone in undergoing cosmetic treatments as his 'wife' Susie Bradley, 25, has also used Botox in addition to getting a boob job.   

'The reason why I got my boobs done, in complete honesty, is before I had my daughter, I only ever had little boobs,' she recently told Who magazine.

'But after I had my daughter and I breastfed – it's a bit gory – my poor little boobs, literally, I could fold them in half. At 23, I felt horrendous.'

The single mum also confessed that she's now considering rhinoplasty to 'fix' her nose. 

'I have a bump in my nose, because it's broken,' she said.

Despite Botox being a common interest for Billy and Susie, the couple have failed to find common ground on MAFS and subsequently their 'marriage' is on the rocks.

During Sunday night's commitment ceremony, Billy chose to leave the show but was forced to stay for another week because Susie opted to stay.
