'Little Britain' star Matt Lucas, Sex Pistols manager Malcolm McLaren and comedienne Joan Rivers have signed up to take party in 'Big Brother: Celebrity Hijack'.
Also enlisted to act as Big Brother to the housemates are 'Match of the Day' pundit Ian Wright, comedian Jimmy Carr, artists Jake and Dinos Chapman, 'Bo' Selecta!' character Keith Lemon and art critic Brian Sewell.
The celebrities will set the tasks, make the rules, hand out punishments and talk to the housemates in the diary room during their stint as Big Brother on the spin-off series.
The contestants on the show will be talented young people, with the group including scientists, acrobats and athletes.
A 'Big Brother' spokesperson said: "Just what they will be getting up to as they take control of the house and who else will join them as celebrity hijackers remains a closely guarded secret."
Dermot O'Leary will present the series, which is due to begin on E4 on 3 January.
