Early in the morning, Casey is on the sofa talking to Sam Faiers about feeling the need for sex.
Casey says: “I woke up really horny this morning. Like, ridiculously.”
She adds: “I just had to get my mind off of it and think about something else.
Later, Casey is drinking champagne in the large task room after being locked in along with Luisa and Dappy as part of this week's shopping task.
Casey laughs: “Be careful tonight Lee I’m drinking.”
Lee encourages her: “Have another one.”
Later, Casey is joking around with Lee in the room.
Casey offers: “Do you want a b***job? We’ll call it a treatment, do you want some treatment?”
Lee replies: “A proper treat, as a doggy treat if I had a new one.”
Casey suggests: “I’ll give you a doggy treat. That’s our code name.”
Lee tells her: “Send me straight off to sleep.”
