The islanders played a dangerous game on Thursday (7 July) when the girls had to devise questions to be posed to their partners while hooked up to a lie detector machine.
It ended in tears for Alex and Olivia after the machine claimed Alex was lying when he said he had true feelings for Olivia, found her the most attractive girl in the villa and saw a future for her.
Olivia was devastated by the results and had a bit of a moment in the bedroom, throwing things around to express her frustration.
Alex was also upset about the results and when the islanders tried to comfort him, he took himself off to the corner of the garden to be alone, where he was seen wiping away tears.
"It takes a lot for me to get upset. It's when I really care about someone," he said, adding: "The test can go f**k itself really. I don't give a s**t what the test has to say."
Needless to say, plenty of Love Island viewers took to Twitter to share their thoughts on teary Alex, most of which were: "Oh my gosh, now I'm crying too!" (Us too, us too...)
