Which I’m a Celebrity star will be first voted out of the jungle?

Four I’m A Celebrity… Get Me Out of Here! hopefuls will be spending a sleepless night down under, as the first public vote-off looms.

Last night’s show revealed that either Melanie Sykes, Jimmy Bullard, Tinchy Stryder or Carl Fogarty will be packing up and leaving the jungle on Monday night after their team lost an immunity challenge.

For each round of the Terror Tombs trial, rival teams the Galahs and the Wombats had to spend 15 minutes lying in the dark inside separate coffins, or to outlast their opponents.

Those who went the distance then felt keys drop down from the darkness and the race was on to find the hidden lock in each tomb to escape.

It was not just the claustrophobic darkness they had to contend with: campmates were joined by cockroaches, rats and even snakes.

In the Galahs’ tomb, as rodents squirmed, journalist Michael Buerk called out: “The shorts were a big mistake,” while model Nadia Forde squealed: “It’s down my top!”

But the Galahs won the challenge overall – their second victory of the show.

Earlier the two teams went head-to-head in a Bushtucker Trial worthy of Harry Houdini and his water chamber.

At stake in the all-or-nothing challenge? Dinner for the winning team.

“The Wombats haven’t eaten properly for a good few days now. We are starving,” said Melanie.

Super competitive Carl was the obvious choice for the Wombats, but he turned out to be no match for former X Factor hopeful Jake Quickenden.

At first Jake had his regrets: “It’s kind of hard because Foggy and Jimmy are my two best mates in there, so for us to take meals away, it’s not nice.”

But he quickly added: “I’m absolutely Hank (Marvin). I can’t wait to eat.”

Carl, meanwhile, had a mild case of jungle blues after letting his teammates down.

“I hate coming back and telling the guys I haven’t won it, I haven’t got the food. But we’re fine. We’re a team, we stick together and we move on again for another battle,” he shrugged.

While the victorious Galahs enjoyed an ostrich egg for dinner, the Wombats went to prepare their tucker only to realise Carl had let the side down again by mixing their rations in together.

Melanie explained: “They have different cooking times so between us we had to literally separate the beans from the rice.”

Her teammate, former footballer and I’m a Celebrity favourite Jimmy, is usually known for his sense of humour, but tonight he confided things are getting serious in the jungle.

“Hunger’s kicking in,” he told the Bush Telegraph.

“There’s a few proper struggling now. That’s why we’re gutted, you know. Can you survive? That’s what it’s come down to. Can you survive?”
