Rex and Darnell admitted they struggle with jealousy last night. As the pair were getting ready for bed Rex tactfully tried to tell Darnell - who has enjoyed a flirtation with fellow 'Big Brother' housemate Sara - he might find his relationship with Sara is different when he leaves the house, adding she would probably flirt with other men in front of him.
Rex said: "I'm just explaining to you that you very, very, very possibly might not feel the same way outside. You get all the attention in here."
Worried Darnell replied: "You know me. That could cause a disaster, because I get mad. Like you, I'm a jealous person. I always have been. I get mad."
Rex - who angered many housemates with the way he tried to control his girlfriend Nicole when she was in the house - said it was strange Darnell had made the comment as he had started to think he might seek professional help for his issues when he left the house.
The pair then agreed they were both quite paranoid too, which only made their problems worse.
Rex added: "It's not healthy. I'm paranoid and jealous. I stress myself out."
Earlier, playboy Rex - who has bored the group with tales of his extravagant lifestyle - amazed housemates by claiming he would give the prize money away if he lost the show.
He said: "If I win, I'm donating the money to charity. I'm just humbled by the fact I'm still here."
