'I'm A Celebrity... Get Me Out of Here!' contestants will be forced to eat a crocodile's vagina.

The stars taking part in the forthcoming series of the creepy-crawly show are in for a treat this year as bosses have reportedly decided to shake up their gruesome Bushtucker Trial eating task by throwing in the large reptile's reproductive organ.

A source told The Daily Star newspaper: "In the past, celebrities have had mealworms, witchetty grubs, fermented eggs and fish eyes to eat.

"They're a picnic compared to this delicacy. A crocodile's vagina is something else. Ant and Dec will giggle about it but they don't have to eat it."

But the crocodile's vagina isn't the only thing making it on to the menu as producers are also hoping to bring back some old favourites such as duck feet, pig's testicles, deer blood, cow's udders and baked tarantula.

Details on the forthcoming series, which is filmed in Australia, are being kept under wraps for the time being but a few potential names have been thrown about in recent weeks.

Carol Vorderman is expected to be offered a six-figure sum to take part in the tough reality show later this year as bosses hope she'll draw in male viewers with her "sex appeal".

A source said recently: "She is well-known and still carries a lot of sex appeal.

"ITV chiefs are also hoping that she will be the brains of the camp. She's a TV legend and they're prepared to splash the cash to land her."

As well as Carol, other names in the frame for this year's show include former footballer Robbie Savage, actress Helen Lederer and model Lisa Snowdon.

'Red Dwarf' actor Craig Charles is also rumoured to be returning to the programme.

He previously spent four days in the jungle two years ago but his stint was cut short after his brother Dean tragically died from a heart attack.

And the former 'Coronation Street' star may not be the only previous contestant to make a return to the outback as Spencer Matthews is also in the rumoured line up.

The 'Made in Chelsea' hunk joined the show last year but was forced to leave just a few days into his stint after producers found out he was taking steroids.
