Erin previously revealed to WHO that she hopes to find love through Love Island.
“I’m hoping that because I’m trapped in an amazing villa with people, [then] I have to get to know guys longer,” she said.
“Because normally I do a one date thing or a second date but I would not go on a third date because then that means that I’m just going to start to like you, so I bail.”
