Lemon - whose real name is Leigh Francis - told Good Morning Britain: “Not annoying but Katie Price always comes up as the worst guest, simply because she was so quiet.
“I’ve told her to her face as well, I said, ‘You’re the worst guest because you was so quiet.’
“She had this wall built up around her because she was scared of having the mickey taken out of her.”
Lemon previously told Metro.co.uk he wouldn’t invited Price back on the show, adding: “Maybe it was during her turbulent times with Peter Andre, because he was on with her once and they were just arguing all the time.
“And I couldn’t remember if I thought it was real or for the cameras for their reality programme, but obviously we now know it was real and they were actually falling out.”
The former glamour model - once believed to be worth £40million - was declared bankrupt last month.
Price dodged bankruptcy last December but has failed to keep up with her repayment plan.
She recently had both her pink cars repossessed and her TV series has seen her renovating her Sussex mansion in order to sell the property.
Price is mother to 17-year-old Harvey, whose father is footballer Dwight Yorke, 14-year-old son Junior and 12-year-old Princess with Andre and five-year-old son Jett and four-year-old daughter Bunny with third husband Kieran Hayler.
Price - who has been married three times - is currently in an on-off relationship with personal trainer Kris Boyson.
They announced their engagement in July this year, only to split in November. But they are now thought to have rekindled their romance.
