Kate has complained that PJ and Adele are keeping her awake with their snoring.
She resorted to sleeping on the living-room floor and then in the garden.
Six housemates are crammed into the poor side.
PJ tried to escape the stifling atmosphere in the poor bedroom earlier this week by sleeping on the living-room carpet.
Kate said: "I was lying in my bed laughing so much. I thought he was dying. PJ's snoring is so loud."
Alex told Jade he had heard her in the night singing the Big Brother theme tune in her "baby" voice.
