A host of familiar faces will move into the Celebrity Big Brother house, with a mix of British and American personalities expected.
Contestants taking part will not be confirmed until they enter the house on Thursday night, but a leaked line-up suggested that reality TV stars would be among the latest contingent.
Former Ukip leader Nigel Farage would not confirm or deny that he was turned down by the Channel 5 show's bosses after he reportedly asked for £750,000.
A report in The Sun suggested that he is now holding out to appear on ITV's I'm A Celebrity ... Get Me Out Of Here! later this year after his big money demand was said to be refused.
Mr Farage told the Press Association: "I never discuss private negotiations and as you know, over the last two or three days - or even weeks - there's been endless speculation about the jungle, quarter of a million, now it's Big Brother. So, it's endless speculation about these things and I don't discuss private conversations with anybody."
Asked if appearing on one of these shows is something he would be interested in, he said: "It's never been top of my bucket list, no."
He added: "This is not my priority. I've got lots of things to think about, and rejig and reorganise at the moment, and reality TV is not top of my bucket list."
Mr Farage said he had watched these shows in the past but said: "To be honest over the last 20 years I haven't watched much television, I've been too busy."
He said there had been "endless" stories about him and reality television, adding: "Whether they're true or not I'm not either going to confirm nor deny. I would never discuss any discussions I have with anybody. I'm very, very, very private like that."
American personalities rumoured to be appearing on Celebrity Big Brother include Danity Kane singer Aubrey O'Day, Mob Wives star Renee Graziano and pop star Ariana Grande's half-brother Frankie.
British celebrities reportedly entering the house include 80s pop star Sam Fox, Anthea Turner's ex-husband Grant Bovey and Geordie Shore regular Marnie Simpson.
:: Celebrity Big Brother starts on Channel 5 at 9pm on Thursday.
