Christopher Biggins was removed from the CBB house earlier this week over anti-semitic comments, and contestants have been romping naked on the show.
“They’re real low lives, it’s like they’ve all been raised in a barn," the former Sunday Mirror TV critic said.
"They have no idea how to behave, they are quite repulsive.
“It’s like watching an out of control zoo, it is car-crash television."
O'Sullivan said that the expulsion of Biggins had been an over-reaction by the programme makers.

“I think it’s outrageous that the government seem to be libelling us as a nation.”
