This year's Celebrity Big Brother reality show promises big names and a twisted fairytale theme when it kicks off at 9pm Wednesday, 7 January, on Channel 5.

The show's co-host Emma Willis told the Mirror: "I normally stay very blind to it all right up until the last minute – but this year I've actually seen part of a list very early.

"This is definitely going to be one of the best series of the show. It seems like a proper stellar cast."

Among the celebrities rumoured to be heading into the house are Mel B's husband Stephen Belafonte, Calum Best, former Emmerdale actress Patsy Kensit, and This Morning contributor Katie Hopkins.

Celebrity writer Perez Hilton and ex-EastEnder Danniella Westbrook are also said to be heading into the house on Wednesday night.

Rylan Clark, co-host of the show told Metro: "We've got a very very strong line-up."

"We've pretty much got everyone, but a contestant is never confirmed until they walk through the doors because anything can happen up until the day they go in."

Big Brother talent scout Ros Phillips added: "We're trying to steer away from reality stars but there may be ONE. Maybe not one that's very well-known, it's not your usual line-up!"
