Born-again Christian Stephen Baldwin, hyperactive US rapper Sisqo and veteran socialite Ivana Trump are all vying to avoid being voted off from the show.
The contestants spent the majority of the day winding down from Thursday's task of being made to attend a themed "tarts and vicars" tea party.
Earlier this week London-born rapper Lady Sovereign was booted out.
Afterwards she protested that she had been bullied by other contestants because of her "outspoken" nature.
The singer - who was evicted from the show on Monday night, with 69.5% of the public vote - was nominated by the housemates to face the public vote after stealing food and being accused of not pulling her weight with household chores.
Ronnie Wood's ex-girlfriend Katia Ivanova was the first housemate evicted from the show.
The 21-year-old Russian cocktail waitress was followed out of the house by the second contestant to be kicked out - former Hollywood madam Heidi Fleiss.
