Married at First Sight has been a huge hit on E4 with couples brought together by experts to make the ultimate commitment to each other.
The show sees complete strangers meet for the first time on their wedding day and make lifelong vows to each other.
The contestants have lavish weddings, complete with the dress, suits and reception at a beautiful venue.

But lots of viewers were left wondering if the marriages are legally binding or not.
In the American version of the show the couples have legally binding marriages, with them having to officially divorce if things don't work out.
But in the Australian and UK version of the show the marriages are not legally binding, with the couples instead making verbal commitments to one another.
Cast member Nikita Jasmine, who was removed from the show for ‘an unacceptable level of aggression' explained how the marriages worked.
She said: "No it’s not a legally binding contract, it’s a social experiment."
A spokesman for Married at First Sight said: "Following the Australian format, rather than legal marriages, the couples will make a lifelong commitment to one another at a glamorous ceremony, overseen by a wedding celebrant, that includes guests, bridal gowns, dancing, speeches and cake."
