The BBC Radio 1 DJ admitted that he hadn't changed his underwear despite being in Gwrych Castle for three days.
Coronation Street icon Beverley Callard and Paralympian Hollie Arnold MBE decided to do a "mass laundry wash" and asked their fellow campmates if they wanted any of their garments washed.
Jordan, 30, told the pair that he hadn't changed his pants since he's been in the castle, leaving EastEnders beauty Jessica Plummer shocked.
The radio presenter asked Strictly Come Dancing star AJ Pritchard if he’d changed his underwear since arriving at the castle and the dancer said he hadn’t and Jordan was pleased it wasn’t just him.
Jordan said: "Usually at home I wear them once, in here we’ve just gone feral."
Viewers at home were horrified at Jordan's "disgusting" admission and rushed to their keyboards to discuss the bombshell.
Taking to Twitter, one fan penned: "Jordan hasn’t changed his knickers for 3 days???"
A second fan added: "Jordan in the same boxers since going in, the poor chap has been that frightened he's defo touched cloth a few times."
While a third person posted: "Not changed his pants in 3 days and how bad he’s nervous stomach was with the trial."
A fourth said: "I was just about to say Jordan North is a nice lad, but then he said he hasn’t changed his underwear for 3 days."
Fans got to learn even more about Jordan during the Castle Coin Challenge.
Hollie Arnold and Giovanna Fletcher arrived to another room in the castle and laughed as they were greeted by a large painting of all their fellow campmates which had holes where their mouths should be.
The pair were given 10 balls, each with a different quote written on. In order to complete the challenge, they had to successfully match the quote with the correct celebrity by putting the ball into the correct mouth on the portrait.
During the task, Giovanna and Hollie correctly guessed that Jordan was the campmate who had "wet the bed until he was 15 years old"
Giovanna and Hollie had fun together matching all the quotes and successfully completed the challenge giving them castle coins to go visit the Ye Olde Shoppe and cash in.
