Married At First Sight viewers just can't get enough of new groom Josh White's appearance before he starred on the show. 

The hunky 40-year-old thrilled fans on Facebook with his long hair and stubble - with one comparing him to Hollywood superstar Russell Crowe.

In the image, shared to the MAFS Australia Fans Facebook group, Josh looks quite different to his clean-shaven, short-haired look on the show. 

'Looks great' said one person while chimed in 'Reminds me of a thinner Russell Crowe'.

'Having a bit of facial hair is a great look for him too' said someone else, with another agreeing, 'absolutely'.  

It comes after fans expressed their amazement after noticing Josh has two different-coloured eyes. 

'Anyone else notice that Josh has heterochromia! I just noticed,' they wrote. 

The photo was soon liked by many others who commented on how striking Josh's eyes looked in close-up photos.

One fan said Josh's look was 'cool and unique' and another remarked it was the 'first thing' they noticed about him on the show.

Other famous people to have the condition include late cricket legend Shane Warne and actress Kate Bosworth. 

Josh walked down the aisle with frisky bride Melissa Sheppard on Sunday night.

Melissa, 41, is a self proclaimed 'freak in the sheets', and her friends were worried her new husband won't be able to keep up with her. 

The Northern Beaches hairdresser and the 40-year-old advertising client director seemed like an odd match at first.

Melissa insisted she wanted a 'Thor' or 'Gladiator' type man with 'hair on his chest' - but shy and sweet Josh doesn't seem to fit the alpha male bill. 

But she was surprised by how much she liked her husband, calling him 'such a gentleman' for the chaste peck he offered her at the altar. 

When it came time to kiss the bride, Melissa was all in, smooching Josh passionately and groping his bottom. 

Josh was impressed by Melissa, telling producers, 'Everything about her was exactly what I was hoping for.'
