More Celebrity Hijack names revealed

More star names have been added to the list of those taking part in Big Brother: Celebrity Hijack, which begins on January 3 on E4.

Little Britain star Matt Lucas, art critic Brian Sewell, football pundit Ian Wright and Bo Selecta! character Keith Lemon will join the already confirmed likes of Malcolm McLaren and Joan Rivers in the new show - which will see celebrities taking over the role of Big Brother and giving the orders to a group of new housemates.

More celebrity names are also expected to join the show, which will run for one month - but their identities are being kept under wraps.

"Just what they will be getting up to as they take control of the house and who else will join them as hijackers remains a closely-guarded secret," said a Channel 4 spokeswoman.

The contestants for the show are also being kept under wraps but are expected to include young scientists, athletes, acrobats and Mensa members.

Dermot O'Leary will present the show, with Davina McCall returning to front the main series in the summer.
