I'm A Celeb's Helen Flanagan said she felt "sick" watching a fellow contestant tackle their terrifying first trial 2,000ft in the air.
In action-packed scenes tonight, the horrified actress watches athlete Fatima Whitbread taking part in the first challenge to earn a meal - but it left her feeling very queasy.
Fatima was climbing along balls suspended hundreds of feet in the air as she tried to earn stars for the campmate's food.
Phil Tufnell asks Helen if she's "alright as she says: "I feel sick."
She then leans over and faces away from the trial, unable to watch.
Helen first took part in I'm A Celebrity... Get Me Out Of Here! back in 2012 when she was just 22-years-old.
She knew the show was hugely popular and that it had the power to boost her career, but it wasn’t until she started watching clips on YouTube that reality began to dawn on her.
Helen said: "I just got absolutely destroyed. It was just ridiculous. I was just like, 'Oh, I’ll be fine. I’ll chill in my bikini, make some friends, it will be good for me…' I’d watched a few episodes but I didn’t watch it in detail. I was only just YouTubing things when I was on my plane, then I was thinking, 'It won’t be that bad'."
However, she didn't know what she had got herself into as she said she was "horrified".
She added: "I was horrified. I’ll never forget it. When I arrived at the camp there were rats everywhere.
"I’d never seen a rat. I was just absolutely thrown. I felt sick. I was so scared. I was just horrified by everything."
As she entered the jungle, viewers cruelly voted for her to do trial after trial, Helen said: "I just got voted and voted and voted and I really struggled with everything."
Now, ten years on, Helen has gone back to the jungle for the first I’m A Celebrity all-star edition.
She explained: "I thought about it for a good while. I did the jungle when I was 22. And now I’m 32. Obviously you change, you’re such a different person within 10 years.
"I really wanted to set myself the challenge of doing it. I’m A Celebrity is such an iconic show and it’s so flattering to be asked back."
