The thirteenth series has already gained a host of celebrity fans, who tuned in and took to Twitter to share their excitement and views.
TOWIE star Joey Essex is already favoured to win and provided much entertainment from the start of the episode, with the television personality filmed screaming and skydiving out of a helicopter.
"@JoeyEssex_ you're making me laugh Boi," tweeted Made in Chelsea's Jamie Laing.
"Crying my eyes out watching @JoeyEssex_ jumping out the helicopter so proud of my baby brother WOW so brave x so brave x," wrote his sister Francesca Essex.
"Good Luck @JoeyEssex_... I literally cannot wait to watch!! #imaceleb," posted his co-star Lucy Mecklenburgh ahead of the show.
Amy Willerton, Alfonso Ribeiro, Kian Egan and snooker player Steve Davis were just some of the other famous faces who made their debut on the show.
Joey and Steve are filmed meeting at the start, with the pair being placed in the same team.
"The reflection of your teeth is blinding me," Steve told Joey as they met. According to the snooker player, the duo had come up with a clear strategy on how to reach camp first.
"It's important that we reach checkpoints because Joey has told me that he wants to pick birds that are well fit," said Steve.
The pair won the first leg of the race, picking Olympic Gold medallist Rebecca Adlington and later Miss Universe GB Amy for their team.
"I'm so glad we've got Amy," said Joey, clearly taken by her beauty. "She's a proper sort."
Later that evening as rain lashed the celebrity camp, Joey and Amy grabbed the opportunity to cuddle up for warmth. The pair had already bonded, with the stunning model teaching Joey how to tell the time.
"It's so much easier to look at your phone though, isn't it?" said Joey.
"You ought to remember, if you want to go and buy a nice watch, like a nice designer watch, people will come up to you and say, 'Joey, what’s the time?'" said Amy.
"I've got a watch, but watches are more like fashion, aren't they?" said Joey. "My watch ain't got numbers on it."
A jungle romance may be on the cards, but that didn't stop Joey's ex-girlfriend and co-star Sam Faiers from showing her support.
"Home time :-( back to reality. Heard @imacelebrity has been good. Good luck @JoeyEssex_ we're all supporting you," tweeted Sam.
