The 75-year-old horse-racing pundit took part in the 2005 series of 'Celebrity Big Brother', and is making a return to the show as part of the latest 'Time Bomb' twist, as the Borehamwood house is set to be transformed into the 'Hotel From Hell', in which a number of former 'Celebrity Big Brother' housemates will be popping in over the next week.

John originally lasted 12 days in the house, and is best remembered for walking around in his underwear, picking his nose, and staging a protest over not getting any Diet Coke in the house.

This will be the second time John has returned to the house, as he starred in 'Ultimate Big Brother' in 2010 as well.

The Channel 5 show's 'Hotel From Hell' twist follows the departure of legendary housemates Helen Wood and Nikki Grahame - as well as Brian Belo, who escaped over the wall - who visited the house that made them famous for two weeks. Fellow legendary housemate Aisleyne Horgan-Wallace - who was first in series 7 of the show - is still in the house.
