There are some pretty impressive CVs in camp this year, but what exactly do our Celebrities do when they're not fending off mosquitos and eating camel hooves? Take a look through our gallery of 2013's contestants in their natural habitats.
Now this is the story all about how... Alfonso Ribeiro's life got flipped, turned upside down when he first stepped onto the boards on Broadway as a young kid. We know him best for playing Carlton for six years on the Fresh Prince, though, and bringing that dance to the masses.
Our resident hotty Amy Willerton is no stranger to a barely-there bikini - having been crowned Miss Universe GB and winning Katie Price's reality TV search for a model - so watch out for plenty of slow-mo shower scenes.
Welsh-born fashion designer David Emanuel was not only the mastermind behind Princess Diana's elaborate wedding dress (complete with 25ft train!), he also set up his own line when he was only 25 years old. Now just think what he could create with a couple of hammocks and a palm leaf...
Set to be the reem-est campmate of all time (sorry, Mark Wright), when he's not in the jungle, TOWIE's Joey Essex is mostly coming out with some amazing one-liners (yes, the lad thinks Danish bacon is from Germany) and inventing his own vocabulary on the hit reality show.
12 years, 11 albums, 45 million records sold and 14 UK number ones: it's fair to say that Westlife alum Kian Egan has had a successful pop career, culminating in the band's last ever tour earlier this year.
From Albert Square to the Australian outback, Laila 'Big Mo' Morse has played EastEnders' very own Del Boy for the past 13 years. Fun Laila fact? Hollywood megastar Gary Oldman is her brother!
The outspoken and controversy-courting Matthew Wright was a former gossip columnist and talking head before he began presenting his own daily current affairs show - which has been on air for the last 13 years. With a sharp tongue like his, all we can say is bring on the camp fireworks...
With four Olympic medals and an OBE already under her belt at the tender age of 24, our swimming champ Rebecca is more often found underwater than in the jungle. But now she's retired from competitive sport, could her athletic ability be the camp's secret weapon for those all-important stars?
As sport's first ever millionaire, Steve Davis has won more professional titles than any other snooker player, and an OBE - but now he's hoping that he can pot the title of King of the Jungle this year.
As Emmerdale's Chastity 'Chas' Dingle, Lucy's lived through a murder accusation, her son's almost suicide, several affairs and two marriages - a fine preparation for the drama that the I’m A Celebrity... jungle will be throwing at her.
