Celebrity Big Brother returns this Sunday night and insiders say that we can expect some serious surprises for the final series.

The Daily Star reports that housemates will face all new evil challenges including handling a tarantula, drinking disgusting cocktails and a strip poker style task.

“The theme for the final series of Celebrity Big Brother is ‘Hell Lies In Others’,” a source told The Daily Star. “They have spent the year being pampered and enjoying a luxury lifestyle but once those doors to the house slam shut, they may well regret ever entering.

“We’re going to have some extra live shows fitted into the TV schedules where Davina McCall will call up the house and unveil a shocker for them – a live task. To fail could lead to a series of forfeits including losing all your clothes or even facing eviction.”
