The first series went all out, with the couples having mini wedding ceremonies – in astonishing scenes, the girls even went shopping for wedding dresses and bought bouquets.
It all got a bit much for Jon Clark of that series, who got down on one knee and actually proposed to girlfriend Hannah Elizabeth in the final episode (they broke up shortly afterwards).
The following series haven’t been quite so extra about the final coupling, instead opting more for a prom-style celebration – but the girls going shopping for ballgowns and the couples still read vows out to one another, often with tearful results.
What is the twist in the Love Island final?
While nothing has been confirmed for series five, the first four series of Love Island saw viewers vote for their favourites of the four remaining couples to decide a winner.
The two halves of the winning couple were then each issued with a card by Caroline Flack, reading ‘love’ on one side and ‘money’ on the other in a twist straight out of Goldenballs.
If both couples choose love, they split the £50,000 between them.
Should one pick love and the other money, then the one who picked money walks away with the full cash prize.
However, if they both pick money, both partners leave empty handed.
For the last four series, all couples have split the money between them but could series five see a shock ending?
