Celebrity Love Island involves a group of 12 celebrity contestants, referred to as Islanders, living in isolation from the outside world in Fiji, constantly under video surveillance. To survive in the villa the Islanders must be coupled up with another Islander. On the first day, the Islanders couple up for the first time based on first impressions, but over the duration of the series they are forced to "re-couple" where they can choose to remain in their current couple or swap and change. Any Islander who remains single after the coupling is eliminated and dumped from the island. Islanders can also be eliminated via public vote, as during the series the public vote through the Love Island app available on smartphones for their favourite couple, or who they think is the most compatible. Couples who receive the fewest votes risk being eliminated.
