The model told Sara that the other housemates had been quizzing him about his feelings for her and confessed that he did have a crush on her.
Arron told Sara: "They have been asking me loads of questions, especially Ashleigh. Loads of strange s**t. 'You two have got a lot in common', 'blah, blah, blah', 'Do you like Sara?'"
"What did you say?" asked Sara.
He replied: "I said, of course I do. She's really f**king attractive. What's not to like about her?
"I normally get dead-awkward and uncomfortable about it, but it's different in here. On the outside, I'd probably try to say something dead-cheesy to you. I'd probably try and make you laugh a lot.
"If it's on the outside, we'd suffer from the awkwardness and we'd have a laugh and a giggle. On national TV, it's a different story. Do you know what I'm saying? Whatever I say, everyone else sees it on telly, so I make myself look like a t*t."
