Ahead of the new series of I'm A Celeb, Christopher talked about his experience on the show in 2007, which he won.
The actor and TV presenter took part in the seventh series of the ITV show, and just pipped supermodel Janice to the post, leaving her as a runner up.
Speaking on ITV's This Morning, Christopher said he wish he had known he was going to be in the jungle with Janice.
"I wish I'd known that I was going to work with the horrendous Janice Dickinson," he said. "She was so vile, she was so horrendous, she was so... everything. When I was in the final with her, I honestly believed she was going to win, but thankfully I did, and she lost."
Former King of the Jungle Christopher also said the lack of food at times was "horrific" and the level of boredom was very high.
The new series of I'm A Celeb kicks off this weekend. ITV have confirmed the full line-up of 10 celebrities, who are: Tony Hadley, Yvette Fielding, Chris Eubank, Jorgie Porter, George Shelley, Kieron Dyer, Lady Colin Campbell, Duncan Bannatyne, Brian Friedman and Susannah Constantine.
Two more celebrities are also expected to make a late arrival in camp.
I'm A Celebrity... Get Me Out Of Here! returns on Sunday 15 November on ITV at 9pm.
