Comedian Iain Lee has called Rebekah Vardy a "bully, a liar and a manipulator".
The radio presenter took part in the 2017 series of ITV jungle reality show I'm A Celebrity...Get Me Out Of Here! at the same time as the footballer's wife at the centre of the Wagatha Christie trial.
Lee, 48, revealed on Twitter that he had been approached to do an interview about Vardy in relation to her promotion of mental health.

He tweeted: "Just had an interview request to talk about how Rebekah Vardy is so brave for promoting mental health... she contributed to me being f**king miserable and isolated in the jungle...so, that's a pass from me."
Lee then shared his reply to the request in which he said, "I feel I have to explain my refusal."
He went on: "I don't know if you saw any of I'm A Celebrity when I was in there. Vardy was a bully, a liar and a manipulator. She was part of a team that targeted me and made much of my time in there miserable.
"Her first comment to me was 'I think you're a bit of a t**t'. She encouraged people not to talk to and left me isolated (apart from two camp mates who were not taken in by her).
"When she came out of the camp she told lies about me. She bullied my sister who was staying in Australia and told her 'in my world, men don't cry'.'
"Part of me hopes your email is a ruse to get an interview from me which I think is about her bravery and they you skewer to make it about her bullying and belittling.
"I hope the latter is correct because if you are trying to show her as a mental health ambassador, I'm afraid you couldn't be further from the truth."
Vardy is married to footballer Jamie Vardy.
After she became the third celebrity to be voted out of I'm A Celebrity she claimed scenes had been cut from the show to make it look like she had bullied Lee.
Vardy — a mother-of-five and an ambassador for children's charity Barnado's — became frontpage news in 2019 after Coleen Rooney announced on social media that Vardy's Instagram account was responsible for leaking her private posts to The Sun newspaper.
Rooney revealed she had narrowed down a list of suspects who had could be leaking her private posts to just one by gradually removing followers and posting fake updates, hence the 'Wagatha Christie' nickname.
Vardy went on to sue Rooney for libel in the High Court ,with the public eagerly following the minute details of the case – including Vardy's private Whatsapp messages – at the Royal Courts of Justice in London in May.
Judge Mrs Justice Steyn is expected to give her decision in writing at a later date.
