The Ultimatum: Marry or Move On

Nick and Vanessa Lachey host this social experiment where single men and women look for love and get engaged, all before meeting in person.

The singles talk to a stream of potential love interests and when back in the real world, as the couples plan towards their wedding day, they will quickly discover whether they can turn their emotional connection into a true love before the fast-approaching ceremony.

Get hitched or call it quits? Couples put their love to the test — while shacking up with other potential matches — in a provocative reality series.
