Kim Kardashian's BFF and former Hollywood publicist Jonathan left the house on Monday after just six days.
In his first interview on Bit On The Side, Jonathan said: "Oh my god, it's like hell in there!"
However, he did admit that it was "fun" in the house: "We had the best times in there. It was amazing that there was so many fun people, it was such a great group, and not a trashy, filthy group."
Host Rylan Clark-Neal asked Jonathan: "When you contemplated leaving, did you think what would Victoria Beckham do?"
Well, Jonathan said he did!
"I thought, Victoria Beckham would put her sunglasses on before she left. And I did put my sunglasses on! Honestly I was teary eyed to leave so that's why I put my sunglasses on. You really grow so close to these people, no one will ever understand until you live in there."
Jonathan also said that having watched the American version of Big Brother, nothing could have prepared him for coming into the house.
And talking about his close bond with Gemma Collins, he said he will "absolutely" meet up with her on the outside.
Jonathan admitted that he actually watched Gemma in the helicopter on I'm A Celebrity, and instantly knew that he would get along with her: "I thought, that's my type of girl, that type of comedy is perfect. She makes me laugh."
