The celebrities taking part in Big Brother CELEBRITY HIJACK have been banned from giving the housemates sexy tasks when they take control.

This follows a request from a male celebrity to make two female contestants kiss one another.

"Celebrities can't give out any sex-related tasks,'" a show insider told NOW magazine.

"The housemates can't be asked to do anything that they might be uncomfortable with."

Tomorrow, self-confessed sex addict Russell Brand will be dishing out orders to the gifted housemates and BIG BROTHER bosses are said to be particularly concerned about the tasks he will set.

A source told the Daily Star: "Russell is extremely cheeky so we're prepared for some near-the-knuckle tasks."

Meanwhile, Kelly Osbourne was the latest celebrity to take over the BIG BROTHER house.

The daughter of legendary rocker Ozzy Osbourne treated the housemates to a gothic-themed party complete with leather outfits, blood-red cocktails and a skull ice sculpture.

Jeremy and Victor were told off by fellow housemates Jay and Calista after it emerged they had drunk all of the alcohol provided.

Radio DJ Chris Moyles has been revealed as the celerity hijacker for Sunday.

He has been musing over potential tasks for the unsuspecting housemates during his daily Radio One breakfast show.

An E4 source told the Sun: "Chris has been watching the show and has loads of ideas for funny tasks. He’s really excited about getting in there and mixing things up."
