Actor and singer Jason Donovan has been lined up to enter the jungle in ITV's I'm a Celebrity Get Me Out of Here! reality TV series.
Liza Minnelli's ex-husband David Gest, Myleene Klass and former Busted star Matt Willis are joining the show.
Prime minister Tony Blair's sister-in-law, Lauren Booth, will also be taking part.
Donovan, 38, has already been tipped to win, with bookmakers Ladbrokes making him the 2/1 favourite.
The former Neighbours actor said: "I want my own character to come across, my own identity, whatever that is."
Radio and television presenter Toby Anstis and comedienne Faith Brown are also set to go into the jungle.
They will be joined by fashion designer Scott Henshall, former news reader Jan Leeming and Footballers' Wives and The Bill actress Phina Oruche.
Gest, 53, best known for his brief marriage to singer Minnelli, which lasted only a year, admits he has not washed up dishes in 25 years. He said: "How am I gonna cope without a maid?"
The programme's presenters Ant and Dec, who recently won the most popular entertainment presenter gong at the National Television Awards, will be back to host the show.
A selection of the most popular Bushtucker trials will again feature.
Past series have seen celebrities challenged to eat a selection of grubs, cross ravines on tightropes and handle snakes.
The show's executive producer, Richard Cowles, promises there will be a few twists and turns along the way this year.
"There is one big, never before seen surprise for the celebrities and whether it's a welcome one remains to be seen," he said.
The new series begins on Monday at 2100 GMT on ITV.
