The former ‘Top Gear’ star, 63, was working on 'Sand Job', the penultimate episode of their Prime Video show, but he and his co-presenters James May, 61, and Richard Hammond, 54, were so dehydrated during the trip, that they were unable to relieve themselves for a long time.

According to the Daily Star newspaper, he said: “We drank litres and litres of water, and we didn’t pee. I mean, I don’t know where it was going.

“Hammond said after three or four days, ‘I’m going to have to pee.’

“I suddenly thought, ‘I haven’t had a pee this whole time.”

James agreed and added: “We did go a few days without a proper wee, and I’m someone who likes to urinate freely. I mean, not in my trousers, but I don’t like to hold it in.

“When we did a wee, it sort of came out as dust.”

The special will see the trio follow the footsteps of the legendary Paris-Dakar rally, in which they must complete the journey in cheap modified cars.

Jeremy, Richard and James will also traipse across the Sahara Desert and cross dangerous rivers, all whilst protecting their fuel container from exploding.

The petrol head admitted that the journal had been “b****y tough” for the whole production team.

He said: “You know, the funny thing is you don't get filthy in a desert. It's a very strange thing but sand is incredibly clean.

“We’ve experienced this in the Atacama and the Gobi and the Nomad and all the places we've driven over the years. You don't get dirty. But it was b”****y tough.”

‘The Grand Tour: Sand Job’ releases on Prime Video on February 16.
