In each season, three couples are paired up by relationships experts and agree to marry when they first meet. Complete strangers become husband and wife in a matter of seconds, and then their lives are documented by cameras over the course of about six weeks.
The couples enjoy their first night together in a hotel after exchanging vows -- and some decide to have sex -- and then they embark on a honeymoon, move in together, and simply attempt to conquer the struggles of daily life as man and wife.
At the end of the extreme experiment, each couple must decide whether they'd like to stay married or get a divorce.
Married at First Sight has had mixed results over the last few years. While many pairs choose to stay together and continue on with married life at the end of a season, the real world away from cameras seems to hit them hard, resulting in a split months later.
Do cast members see a different side of their spouses once cameras are turned off, or do the romances naturally fizzle over time?
Some couples are still together to this day and are extremely happy. Jamie Otis and Doug Hehner from Season 1, for example, are overjoyed about having just welcomed their first child together in August 2017, a baby girl they named Henley.
But then there are Married at First Sight relationships that ended badly. Jessica Castro from Season 2, for instance, accused her ex-husband Ryan De Nino of alleged death threats, and she went on to file a restraining order and lawsuit against him.
Are the remaining Married at First Sight couples lovers, friends or enemies?! What is the current status of each relationships now?!
