Sophie is currently coupled up with Tom Powell, and as romance seems to be blossoming between the pair, she decided to be honest with him about her past relationships.
Last night (2 June), viewers saw Sophie nervously tell Tom her last relationship was with a girl. She admitted she was worried about how he might react, but Tom reassured Sophie her history doesn't change a thing.
Speaking privately with Tom, Sophie told him: "I was in a relationship with a girl before I came in here."
When Tom asked her if she is bisexual, Sophie told him she wasn't but didn't want to talk about it. She confessed that she was "scared" about telling Tom about her previous romance, and said: "I just thought that I would get it out in the open. I'm worried that it would put you off."
Tom reassured Sophie it hadn't. He replied: "Why the hell would that put me off? I don't think you should be ashamed of any part of your life. Especially that. There's nothing to try and hide. You don't have to worry about anything."
"That was a massive worry for me coming in here," Sophie said. "I feel better. I feel like I can talk to you about anything."
Recalling their conversation in the beach hut, Tom seemed pleased that Sophie had chosen to open up to him.
He said: "I think I've gained her trust... She said earlier that she trusts me and she feels so comfortable and relaxed around me."
Sophie, meanwhile, said in the beach hut: "It was nice to be open and honest... we've formed a closer bond today and I'm liking where it's going."
