Mark "The Beast" Labbett talked Anne Hegerty into starring on "I'm A Celebrity... Get Me Out Of Here!"
"The Chase" star revealed on Wednesday's episode of ITV's "Loose Women" that he thinks his co-star "will go a long way" and admitted he felt "guilty" after voting for her to take on a Bushtucker Trial.
Speaking on the show, Mark said: "I've got a confession to make, I kind of talked her into it. I feel even more guilty after voting for her on that trial!
"Foolish me, when they said "mental challenge" I thought, "Perfect for Anne, throw her in, she's really good under that kind of test conditions!"
"I should have realised, with it being the jungle, it would be more than solving a problem, it would be slime etc!"
Mark, 53, is backing Anne - who is nicknamed The Governess, to be named Queen of the Jungle - and has confessed the she "plans everything" but is "confident" that the star will be absolutely "fine".
He added: "People with autism, they like certainty, they're the ultimate planners. The business we do [as quizzers] it's very easy to absorb facts with clear answers.
"Anne does really badly when she's surprised. She plans everything. I know everywhere she goes in the world, before she goes she will plot where she will have mass on the Sunday.
"She will have on Google maps the church she will go. She's already bought my son his birthday and Christmas present before she left - that's organisation.
"You'll notice with I'm A Celeb, anything that comes out of the ordinary, she doesn't react well to it. I'm quite confident in her ability to recover from that. I think she'll be fine."
