The pair's relationship seemed to blossom with them both handcuffed together, but now they're free Lee has admitted to wanting nothing more.
He told some of his fellow housemates behind Casey's back yesterday: "I can't sleep with her now because its' just stupid.
"I just don't want it and it's not what I'm here for. I'm not here for a f**king relationship on TV."
He insisted there was nothing to be read into his actions with the model, saying: "I cuddle everyone, I cuddled up to Ollie the other night.
"It makes me sick... the idea of it... and I cant run anywhere either. Normally I just run."
But Lee insisted it wasn't Casey's fault, adding: "It's not her, shes a lovely girl, she;s really sweet and she makes me laugh, she's really funny."
In yesterday's show we saw some of the other housemates cause doubt on the romance.
“Watch how much they turn it up now they are up for eviction," Luisa told Jasmine. “The love birds.”
Jasmine asked: “Were they having sex last night?”
“Course they weren’t having sex, I doubt they even fancy each other," snapped Luisa. “I think Lee has realised it’s one of the only ways to stay. It’s like the oldest trick in the book. If we had some lesbian thing we’d win.”
