Yvette became the third celebrity to be voted out of the jungle, and now she has lashed out at Lady C (who has since left on medical grounds), claiming the 66-year-old insulted her.
Yvette claims show bosses cut out footage showing Lady C hurling insults at her which are too personal to repeat.
"It was about myself, my career. It was said with such venom," Yvette told The Sun. "I thought, 'I cannot cope anymore - you are a very rude woman'. You see this eccentric old lady but she switches just like that.
"She tells lies too. I do not want anything to do with her."
Reveal have contacted a rep at ITV for comment.
On Wednesday (1 December), show bosses announced Lady C had left the jungle. Her agent has since said she had suffered a fall in camp, and that Lady C claims she was bullied by two campmates.
A spokesperson for Tony Hadley has since denied the accusation, calling Lady C's claim is "pure fantasy".
