Big Brother baddie 'Nasty' Nick Bateman will re-enter the house this week to perform a task.
The former contestant returns to the show to mark its tenth anniversary.
On the same day, a group of three ex-housemates from BB3 will take part in an egg and spoon race.
Nikki Grahame and Brian Belo will also revisit a memorable task from their year on Wednesday.
Nick was booted off the show for writing notes to contestants to influence voting.
