Lady Colin Campbell quit the jungle on medical reasons, with her agent later confirming she had suffered a fall in camp, before saying Lady C felt she was being bullied by two campmates.
Her agent Mike Hollingsworth said on This Morning: "She's left because of a medical condition. I know she suffered a fall in the jungle camp and because of that viewers have seen she has been using a special chair to sit on. That's clearly got a bit worse.
"She is sad to be out, but the medical condition might have been exacerbated a bit by a bit of bullying she thinks she has received by two campmates in particular."
No campmates were named, but over the last two weeks Lady C has been at loggerheads with Duncan Bannatyne and Tony Hadley.
A spokesperson for Spandau Ballet star Tony has now dismissed Lady C's accusations of bullying as "pure fantasy".
Tony's spokesperson said: "These allegations are pure fantasy - the whole nation has witnessed how Lady C has continually made vile and hurtful comments towards various camp-mates. To make accusations of bullying and biased editing is unbelievable and disrespects both the show, and the millions of fans who have tuned in and voted night after night."
Constant war of words in camp has seen Lady C blast Tony as a "buffoon" and call Duncan a "vain old goat". In recent days Lady C has refused to acknowledge Duncan and Tony, and they have aired the same views.
Tuesday night's show saw Chris Eubank voted out of the jungle. Tony and Duncan remain alongside Jorgie Porter, Ferne McCann, Kieron Dyer, Vicky Pattison and George Shelley.
