Richard Madeley has been rushed to hospital overnight after falling ill in the I'm a Celebrity camp in Wales.
The 65-year-old was sent to A&E after worrying production staff and his fellow co-stars with the sudden illness, The Sun have reported.
A source told the publication: "It was horrifying - campers were really upset and concerned, all of the crew and medics rushed to set to help him."
They continued that it was a "real scare" for everyone and that he was taken to a nearby hospital as a precaution but is now on the mend.
It comes just after Richard took part in the Kitchen Nightmares trial, which saw him dive headfirst down a shoot and doused in mouldy fruit and vegetables as he searched for stars, writes The Mirror.
He was left disappointed after returning from the trial with only four stars out of ten after struggling to untie knots.
Richard appeared to be in good health during the trial and was seen laughing and joking with Ant and Dec throughout.
An ITV spokesperson told the publication: "Richard was unwell in the early hours and was immediately seen by our on-site medical team.
"He's since been taken to hospital as a precaution, the health and safety of our campmates is our priority."
Before entering Gwrych Castle, Richard said that he wanted to be voted to do trials.
“I really hope I do get voted for the Trials," he said.
“The thing about this programme is you mustn’t go in to it if you take yourself remotely seriously. I don’t and I am thoroughly looking forward to being covered in god knows what!
“You have to be prepared for people to laugh and I see this as a bl**dy great romp of fun!”
