CELEBRITY Big Brother will be more unpredictable than ever when it returns this week – sparking fears housemates will crack up because of the pressure.

Show bosses are planning extra surprise evictions – meaning the celebs will constantly be on their guard.

A Big Brother source last night revealed: “Producers have ordered more live evictions. They will be dropping like flies after just days in the house.

“They’ve all got big egos and want to make the final. So the constant threat of eviction and a booing crowd will make them nervous.”

Show host Brian Dowling, 33, has also promised the famous housemates will be given a rough ride on the new series of the hit Channel 5 show.

He revealed: “The whip will be cracked – we are going to make it tough for them. It’ll be hell living in that house.”

Thursday’s launch show will see 12 celebrities enter the house including soap star Natalie Cassidy.

But pals last night feared the former EastEnders actress, 28, would struggle with pressure.

One said: “Natalie has had a difficult year with her ex-fiancé appearing in court for assaulting her and dealing with the break-up. So she could find three weeks in the house difficult and crack up.”

Insiders also fear actress Denise Welch and comedienne Ruby Wax, 58, who have both battled mental illness, will find it tough on the show.

Other stars who are lined up for the series include Reservoir Dogs actor Michael Madsen, 54.

Celebrity Big Brother begins on Thursday at 9pm on Channel 5.
