Love Island (Series 4)

The fourth series of Love Island aired on ITV2 from June 4, 2018 to July 30, 2018.

The series was hosted by Caroline Flack and narrated by Iain Stirling. The winners of the third series were Dani Dyer and Jack Fincham.

The series opener received the highest rating on a digital TV programme since the 2012 Summer Olympics were broadcast on BBC Three; it was also the most watched programme ever on ITV2.

Casa Amor
On June 27, 2017, it was confirmed that ‘Casa Amor’ would be reintroduced following its success during the previous series. It is a second villa featuring new Islanders in a twist designed to put the couples to the ultimate test. Twelve new Islanders were introduced during this twist. The villa was called ’Casa Amor’ which translates to ’Love House’, and is located not far from the main villa. The new Islanders for the twist included six girls; Charlie, Darylle, Ellie, Grace, Kazimir and Savanna, as well as six boys; Alex, Charlie, Dean, Frankie, Jack and Jordan.

The twist came to its conclusion four days later when the original Islanders were given the choice of remaining with their current partner in the opposite villa or couple up with one of the new Islanders. However, as they were living in separate villas, they were not aware of each other's choice. If one decided to re-couple and the other did not, then the one that didn't would be single but still remain on the island. If both re-coupled then they would both remain in the villa with their new partner, and any remaining single new islanders would be dumped. At the end of this, Georgia and Wes became the only single original Islanders, and Charlie W, Dean, Jordan and Savanna were dumped.
