The contestants for the upcoming series have not been revealed but there have been plenty of rumours about TV star Madeley being among the line-up.
And Haskell – who is married to Madeley’s daughter Chloe - seemed to confirm it in a slip of the tongue on Good Morning Britain.
“I think he’ll be amazing, and I tell you what, my one thing with Richard…" he said, before Shephard chimed in to ask: “He will be amazing or he might be?”
Rushing to correct his apparent blunder, Haskell said: “He might be amazing. He might be amazing, hypothetically.”
Laughing, he added: “I feel like one of your politicians – 'I didn’t take the money, I didn’t do anything!'"
Madeley has been teasing for weeks that he is taking part in the reality show and signed off from Good Morning Britain last week with yet another clue.
The star, who is one of the show's guest presenters, said: "Now then... I've got places to go, people to see and things to eat... interesting things to eat, so I'll be back very soon after Christmas. This is my last show for a while.”
I’m A Celebrity returns later this month, with Ant and Dec back as hosts.
