I'm A Celebrity's Sue Cleaver nearly died from sepsis after falling ill on the set of Coronation Street.
The actress, 59, who plays Eileen Grimshaw on the soap, is set to head into the jungle in this year's star-studded series.
But it might not be Sue's toughest challenge, as she previously spoke about her terrifying health scare on This Morning back in 2019.
Describing her symptoms, she said: "I suffer, like many people, with IBS and I thought I was having a flare-up while I was working.
"I went in on the Tuesday and late in the afternoon I said: 'Do you need me in this scene because I'm really not feeling great? I need to go home and sleep'.
"My side was sore. Then I came in the next morning at half seven. It was the hottest day of the year but I was on set with a hot water bottle."
Sue said her co-star Melanie Hill, who played Cathy Matthews, pointed out the actress' feet were blue and purple with Sue adding she felt "freezing cold".
The star continued: "I went home after lunch and got into bed and tried to go to sleep. My husband [James Quinn], who also works on Corrie, was on a night shoot and tried to ring me.
"He said: 'Something's not right. I can't hear what she's saying because your teeth are chattering too much.
"He came back and I was just shaking. He rang out daughter, who's a paramedic who said: 'Get her to hospital.' My temperature was 39.9. I didn't know I had sepsis till the next day.
"Immediately I was on fluids and antibiotics. There was an hour window of opportunity."
Having recovered from the terrifying ordeal, Sue has now signed up for this year's I'm A Celeb.
The actress was all smiles as she arrived at Brisbane Airport last week ahead of the show where she'll be joined the likes of Chris Moyles, Charlene White and Boy George.
Sue will also be joined by former health secretary Matt Hancock, who will be heading Down Under in news which has sent shockwaves through Westminster.
Ahead of her own jungle stint, Sue said her only worry about taking part in I’m A Celebrity is the fact she will be filmed 24/7.
“Viewers are going to see a different person to the person they think I am! I am very different. That can be worrying,' she admitted.
“They might decide they don’t like me as much as Eileen!”
“This is the scariest part for me,” she explained. “I am a very private person and I am putting myself out there, which is what I am most nervous about.
“I do keep my life private and I am very happy with my home life."
