Gemma Collins rules herself out of I'm A Celeb return, but who has made the line-up?

Speaking to Good Morning Britain, TOWIE star Gemma revealed, “I was asked to go back in to the jungle but I couldn’t guarantee to producers I wouldn’t walk again so we all made the decision it was best I leave it for this year.”

Gemma famously lasted less than 72 hours in the show before calling it quits last year.

She emphasised it would only be this series that we wouldn’t see her settling down into camp life, hinting that she might yet be up for more bushtucker trials.

There are, however, lots of celebrities who have been spotted touching down in Australia.

While ITV are yet to confirm the full line-up, here are the twelve celebs who are likely to be forcing down kangaroo’s unmentionables this year.

 Duncan Bannatyne

The 66-year-old Dragon’s Den star is used to saying “I’m out” so how long will Duncan last in the jungle once he’s separated from his creature comforts?

Yvette Fielding

Most Haunted star Yvette Fielding, 47, has vitiligo which makes her extremely sensitive to the sun – so the 35 degree heat might prove tougher than the trials for this camper. Perhaps we’ll see the ghost-hunter start to communicate with all the wichetty grubs who’ve lost their lives across the years.

Vicky Pattison

Ex-Geordie Shore star Vicky will be competing for the best bikini body this series. She was known for her drunken antics on the Newcastle-set show, but Vicky’s now a dedicated gym bunny – although she’s not lost her fiery temper.

Spencer Matthews

Made in Chelsea playboy Spencer seems to have made his way through half of Kensington; now he’ll have the pick of the jungle too. He’s worked hard on perfecting his six-pack  so there’ll be plenty of eye candy for female viewers at home.

Ferne McCann

The mouthy 25-year-old will be swapping fake tan for a real bronzed glow as she jets into the jungle. Hopefully this The Only Way Is Essex star will last longer than her sparring partner Gemma Collins, but at least she’ll be guaranteed to ruffle a few feather however long she stays.

Brian Friedman

The X Factor choreographer will have a few choice moves in his repertoire if he needs to quickly duck a shower of cockroaches or a wayward rat in the trials.The dance guru, 38, has worked with Cher, Britney and Jacko so he should have a few good stories to tell too.

Lady Colin Campbell

She’s the 66 year old biographer who exposed Princess Diana’s affair and battle with bulimia to the world. What more secrets will this socialite let slip? And what tales does she have to tell about her own colourful past?

George Shelley

Unless you’re under 18, you’d be hard pressed to remember Union J – who finished fourth in X Factor in 2012 – let alone put names to faces for the four members. This one here is George, 22, who ITV bosses hope will have teen girls glued to the screen.

Kieron Dyer

Former Newcastle midfielder Kieron, 36, ticks the bad boy box for this series. He was caught on camera in an infamous video with Rio Ferdinand and Frank Lampard as well as being banned from driving for a stint after speeding. What headline-grabbing antics might he get up to in camp?

Chris Eubank

The former boxer, 49, and dad-of-four could put the cat among the pigeons with some of his more bizarre takes on life. Not one to mince his words, Chris has reportedly been paid £200,000 to enter the camp so bosses will be hoping for plenty of sparks to fly.

Susannah Constantine

As one half of acid-tongued sartorial duo Trinny and Susannah, the 53-year-old will have plenty of advice on What Not To Wear in the jungle. But will she know how to survive the hunger, tiredness and gruelling tasks? The posh totty will need to pull her socks up in camp if she wants to win.

Jorgie Porter

Hollyoaks actress Jorgie was the first confirmed celeb, called in to replace her ex co-star Stephanie Davis who had to pull out because a severe nut allergy. Not shy about showing off her figure, Jorgie, 27, who played Theresa McQueen, has promised fans will see a fair few skimpy bikinis in the jungle shower.
