Actress Marilyn Galsworthy entered the house earlier today and had to convince housemates she was a celebrity psychic called Shelley.
Jasmine, who was evicted on Wednesday, fed lines to her mother through an earpiece as they delivered psychic predictions to the other housemates.
The pair picked Coleen Nolan and Samantha Brick to potentially win immunity from the next set of nominations, but this won't be granted because Marilyn failed to convince the celebrities she was a psychic.
"Originally I wanted to give [immunity] to Lorenzo, but I'm a bit disappointed he's fallen under Danica's spell," Jasmine said in the Diary Room, as the housemates watched on the plasma screen.
"I think we caused enough trouble. We can't save [Samantha and Coleen] but I wasn't here to save them, I was here to destroy [the others]. We caused mad drama."
Marilyn then realised she'd left her cigarettes in the house, to which an angered Julie Goodyear shouted at the screen: "Yeah, well, they're going in the f**king pool. And your case. Well done, all of us. Like mother, like daughter."
Samantha added: "That's why you recognised her, Ash - it's the eyes, they're exactly the same."
Housemates will be rewarded with dinner, drinks and music later tonight.
