Celebrity Big Brother bosses are now said to be planning a USA v UK theme for this summer's edition of the show.

Producers have been inspired by the way in which American gossip blogger Perez Hilton stirred up so much trouble in the house during the most recent series, and think this new theme could make compelling viewing, dividing housemates into teams based on their nationalities.

A source told The Sun newspaper: "The reason bosses have come up with this idea is because of the impact Perez had on the January series. He was so out there and caused such mayhem that producers want to take it to the next level for the new show.

"They hope that by pitching Brits against Americans they will capitalise on our cultural differences and fireworks will ensue."

And show bosses have reportedly made the decision to book as many "fiery" stars as possible.

The source added: "Usually producers want a mix of contestants with some calmer people amongst the drama queens but this time they have said they want a house full of fiery characters.

"They want it to be one of the most explosive series ever."

It was recently revealed US model Janice Dickinson, 60, has already signed up for the show.

The brunette star - who previously appeared on 'I'm A Celebrity... Get Me Out Of Here!' - has reportedly agreed a £300,000 deal with Channel 5 to enter the famous house.

Janice's rumoured 'CBB' pay packet would be one of the largest in the show's history and comes after former glamour model Katie Price was handed a reported £500,000 to appear on the most recent series, on which she was crowned champion.
