Back with a brand new cast! FYI has announced the cast for Season 4 of its smash social experiment series, Married at First Sight — and it’s heating up in Miami!

From a pool of thousands of hopefuls, six singles (three men and three women) were selected to be paired together in marriage — at first sight. The couples will journey through the ups and downs of their newly-arranged marriages, participating in challenges and completing homework assignments from trained counselors.

The dynamic duos will receive guidance from the show’s standout sociologist, Dr. Pepper Schwartz, as well as two new additions to the MAFS team: Marriage counselor Pastor Calvin Robertson and relationship and communication expert Rachel DeAlto are bringing their expertise to help these couples find love.

Ready to meet the new Married at First Sight Season 4 cast? The Knot introduces them below.
