Over the past week, the original couples have been split up across two villas along with a load of newbies.
In tonight's latest episode, the pot is stirred big time when the original girls in the main villa get a special delivery.
Montana finds a postcard by the door sent from the second villa, Casa Amor. It shows a picture of Kem and Chyna kissing and Marcel, Jonny and Chris in bed with Casa Amor's new girls.
Montana takes it into the garden and shows the other Islanders, repeatedly shouting, “Not good!”
Gabby runs upstairs to get away after seeing the picture of Marcel on the card.
When Camilla and Tyla go to comfort her, she gets upset but they try to reassure her that Marcel must have just been speaking to the girl as a friend.
Later, the girls get a text: “Girls, tonight there will be a Recoupling where the girls will choose to either remain coupled up with their boy who has been living in Casa Amor, or twist and recouple with a new boy. Your decision will have consequences. #stickortwist #headheartdilemma”
All of the Islanders think about what they should do with Gabby questioning Marcel after seeing the postcard.
Could Love Island's only official couple be about to split?
Meanwhile, Amber deliberates over what she should do.
Amber and Olivia talk by the fire pit. Olivia says she can’t risk picking Chris in case he chooses someone else and she loses her place on the Island. She says: “If I hadn’t see that postcard, I would have picked Chris all day long.
"I just have to go with what my gut is telling me but now I’ve seen photographic evidence of him in bed with another girl.”
Amber says she won’t risk it either, despite her heart telling her to go for Kem.
