The daughter of former Prime Minister Baroness Thatcher is among the 10 hopefuls taking part in reality show I'm A Celebrity... Get Me Out of Here.
Thatcher's career includes writing a book on her late father Denis
Journalist Carol Thatcher will be joined in the Australian rainforest by ex-Atomic Kitten singer Jenny Frost and TV antiques expert David Dickinson.
Others include former EastEnders actors Sid Owen and Elaine Lordan.
The producers of the ITV1 show promise "the most ridiculous trials ever" when the series begins on 20 November.
The other contestants are ex-Blue singer Anthony Costa, wine expert Jilly Goolden, former child star Jimmy Osmond, Kimberley Davies, who played Annalise in Neighbours, and Emmerdale star Sheree Murphy.
Thatcher said she would not be "the Iron Lady Junior" on the ITV show.
"I haven't told my mother," she said. "I think she'll think: 'Rather her than me.'
"I think she'll probably be very critical - I can't say it's her sort of show so I might just tell her that I've done it when I get back."
Comedian Joe Pasquale won last year's series
Co-executive producer Richard Cowles said this year's series would be "a lot tougher" than previous series.
"We have some of the biggest, scariest and, in one or two cases, most ridiculous trials ever waiting to greet this year's cast."
Last December's finale drew an average of 10.9m viewers - about four million fewer than the previous series.
Previous winners have included former Atomic Kitten singer Kerry McFadden, former England cricketer Phil Tufnell and DJ Tony Blackburn.
Glamour model Jordan and her now husband Peter Andre, Sex Pistols singer John Lydon and former royal butler Paul Burrell have all taken part in the show.
