‘The Ultimatum’ Season 4 Cast: Meet the Couples & Follow Them on Instagram (PHOTOS)

The Ultimatum: Marry or Move On is back with what is sure to be its most explosive season yet. After all, Nick Lachey kicks someone out in the season preview, so you know this season is bound to be dramatic.

The Ultimatum follows couples at a crossroads. In each duo, there is one partner who eagerly wants to get married, and another isn’t sure about the commitment yet. For the experiment, these couples break up and re-partner with other cast members for “trial marriages.” After their trial marriage, they go through the same process with their original partner to decide whether to get engaged or break up for good.

Season 4 of the dating series is set to follow six couples “gambling for love” in Las Vegas, Nevada. From one couple who met two years ago when she was nannying for his younger brothers to another who met nearly a decade and a half ago in the competitive cheerleading circuit, it’s clear that no couple is safe from their relationship’s toughest decision yet: “Get engaged or walk away forever?”

Below, we’re breaking down everything you need to know about The Ultimatum Season 4 cast, including who’s dating who, who issued the ultimatum in each relationship, and where you can find these daters on Instagram.
