Now, the two have revealed that they plan on getting engaged.
During a game called 'truth bike' on Wednesday's episode, Tayla admitted she would say 'yes' to Grant if he popped the question at the end of the show.
Sitting on a bike position in front of her fellow contestants, Tayla was asked: "At the end of Love Island, if Grant asked you to marry him, would you say yes?"
Giggling at the abrupt question, Tayla rung the bicycle bell to indicate that she would say yes.
Her fellow Islander Justin, was clearly shocked at her admission and pointed out that the end of the show was in just four weeks.
She defended her answer, saying, "Yeah, but you can be engaged for like four years to someone."
Later, to camera, she dded: "I said yes but listen, you can be engaged to someone and have a bloody nice ring on your finger for at least four to five years!"
Meanwhile when Grant was on the bike, he was asked if he was "falling in love with Tayla".
"F**k, that's intense man," he said grinning, before dinging the bell and answering yes.
