It’s a new year, which means it’s time to watch celebrities be stripped of their life luxuries and forced to take part in humiliating challenges, all for our entertainment.

I’m A Celebrity… Get Me Out Of Here!started on Sunday night, and Channel 10 has officially unleashed the constants into the South African jungle. Let’s hope they have iron stomachs.

Hosts Chris Brown and Julia Morris began the new season by announcing that Channel 10 will be matching all proceeds raised for the celebrities’ chosen charities throughout the season to donate to the ongoing bushfire crisis in Australia.

Side note… Watch the promo video for I’m A Celeb. Post continues below video.

There’s been plenty of clues, guesses and rumours, but here’s who is officially in the jungle.

Perez Hilton.

Perez Hilton is the latest campmate to joinI’m A Celebritythis year.

Perez Hilton is a celebrity gossip blogger who rose to notoriety in 2004 for his harsh unpacking of celebrity culture. He has been a fixture in gossip media ever since.

Cosentino.

Australian magician Cosentino is world-famous for his insane, mind-boggling illusionary tricks.

Cosentino came second in the 2011 series ofAustralia’s Got Talent, the season which saw Jack Vidgen take out the title. He also wonDancing With The Starsin 2013.

He joined the jungle a week after the other campmates as an intruder.

Myf Warhurst.

Australian TV icon Myf Warhurst was one of the few celebrities announced prior to the premiere.

Myf is best known for her work at the ABC as a journalist, Triple J radio host and as a team leader on the quiz showSpicks and Specks.

Oh, and she co-hosts SBS’ Eurovision Song Contestant alongside comedian Joel Creasey.

In an interview with Channel 10, Myf explained that although she is a huge reality TV junkie, getting her to take part inI’m a Celeb!took a few years of convincing.

“I always thought I was too scared. I still think I’m too scared, but… I put it down to a mid-life crisis.”

Tom Williams.

Aussie media personality Tom Williams’ arrival into the jungle was similarly announced before Sunday night.

He rose to fame on theMerrick & Rosso show, before receiving his own segment onThe Great Outdoorsand winningDancing with the Starsin2005.

Speaking to Ten about his fear of living in the jungle (or more specifically, his fear of snakes), Williams said: “It will be horrible and I’ll probably be quite disturbed… but that’s entertaining!”

Charlotte Crosby.

Remember when everyone thought the ‘international party girl’ clue was Lindsay Lohan?

It looks like Lilo won’t be making an appearance this year, but we get a pretty good alternative: Geordie Shorestar Charlotte Crosby.

She’s probably one of the biggest reality TV stars in the world, appearing on MTV show’sGeordie Shorefor five years, before moving on toEx on the Beach.She has also hostedJust Tattoo Of Usand won the UK version ofCelebrity Big Brotherin 2013.
