The trio then drove off for the first challenge of the series in a quest to find tokens for their camp.
They were told two of them would have to search through so-called “hell holes” for the prizes, while the remaining member of the group would be forced to plunge their head into a barrel.
Ms Gibson opted for the latter option, saying: “I’ll take one for the team, I’ll take the barrels. I don’t mind sticking my head in things that don’t belong.”
Mr Farage and Ms Rose, 26, meanwhile, had to push their heads inside the “hell holes” and use their tongues to move tokens along a metal wire.
The former politician and Ms Gibson managed to get all three of theirs, earning six tokens for the campmates, while an unnerved Ms Rose was unable to collect any after being confronted with a large number of snakes.
‘Trousers hitched up real high’
Mr Farage had previously turned down offers of hundreds of thousands of pounds from ITV, but reports suggest he will receive up to £1.5 million as a contestant on the popular reality programme.
It is understood the channel’s executives hope that Mr Farage’s participation will attract the same attention as Mr Hancock’s appearance in last year’s series, which resulted in him being stripped of the Conservative whip amid outcry from his local Conservative association and constituents in West Suffolk.
Also appearing on the show this year are EastEnders actress Danielle Harold, radio presenter Sam Thompson, food critic Grace Dent and TV presenter Fred Sirieix, who also all completed a challenge of their own.
Following the tasks, the celebrities made their way to their campsite for the first time and met all their fellow campmates.
Thompson, a former Made in Chelsea star, appeared slightly stunned to discover he would be living alongside Mr Farage.
He said: “You just don’t see that coming. I’m living in a camp with Nigel Farage
“You know when someone’s got their trousers hitched up real high, I was like, yeah, fair play mate.”
