A game of Simon Says turned X-rated when former housemate Paul Danan came back into the compound.
Clearly suffering with an extreme case of the horn, he ordered Jemma Lucy and Sarah Harding to make out.
Paul demanded: “Danan says Sarah and Jemma must kiss until I say stop.”

Paul then made a sleazy jibe: “Make it a good one.”
“You little s***,” Sarah sniped, before launching into a raunchy game of tonsil tennis with her frenemy.
The two housemates locked lips – much to Chad Johnson’s dismay as he looked on with a face like a slapped arse.
After what seemed like a lifetime, Sarah then pulled away and snarled: “I hate you Paul.”
“Sarah and Jemma must kiss until I say stop”
But then Paul dropped the ultimate bombshell.
He started: “The thing is, you didn’t actually have to do that because I only said ‘Danan’ I didn’t say ‘Dangerous Danan’.
“This is ‘Dangerous Danan says.'”
Sarah then stuck her middle finger up at Paul and yelled: “You’re a clever b******.”
