Love Island viewers have urged ITV bosses to "bring back the lie detector" on the show after a series of instalments have seen the islanders seemingly twisting the truth over and over again.Things came to a head in Movie Night when Olivia Hawkins, who has now been dumped with Maxwell Samuda in the latest episode, was exposed for talking behind some of the islanders' backs. As clips were shown of the former islander tattling away to Maxwell about who she thought was compatible and who would go the distance, the rest of villa seemed surprised to learn the truth.
