Richard Madeley has been forced to quit I'm A Celebrity.
The 65-year-old revealed the news on his Instagram account just hours after the news emerged that he has dramatically left the show and been taken away in an ambulance for treatment.
In the update, he insisted that he was "absolutely fine" but that because he had felt briefly unwell in the morning, he was taken to hospital as a precaution.
As a result, he broke his Covid bubble and was forced to leave the castle.
Richard added that he was "gutted" to be leaving as he thanked everyone for their support during his brief journey on the show.
He wrote: "Hello all!
"Richard here - firstly just to say that I'm absolutely FINE. I started to feel briefly unwell in the small hours of the morning and was taken to hospital as a precaution. By leaving the camp, I had consequently broken the Covid 'bubble' and as such I've had to leave the castle and all the wonderful celebs that remain in the camp.
"Obviously I'm gutted to be leaving so soon but the safety of all the campmates is the number one priority. I'm incredibly excited to watch their journey continue.even more so at the prospect of being somewhere a little warmer than Gwrych Castle.
"Thank you to everyone who supported me on my brief but completely unforgettable adventure - I've made some great friends and honestly had the time of my life."
An ITV spokesperson told The Mirror: "Our strict covid protocols means Richard has sadly had to leave the show as he is no longer in the bubble the celebrities form when entering the castle. He has been a truly brilliant camp mate and we thank him for being part of this series."
Earlier today the TV presenter was seen by an on-site medical team before being admitted to hospital as a precaution.
A spokeswoman for the Welsh Ambulance Service said: "We were called at 05.43am this morning, Thursday 25 November 2021, to reports of a medical emergency at Gwrych Castle in Abergele, Conwy.
"We sent a paramedic in a rapid response car and an emergency ambulance to the scene, and one patient was taken to hospital."
An ITV spokesman said: "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."
Wednesday's episode of the show saw Madeley slide head first into a sewer of rotten fruit and vegetables during a trial called Castle Kitchen Nightmares.
The challenge saw the presenter hunt for 10 hidden stars in a room "full of castle critters" as rotten food was dumped on him from above.
Madeley, best-known for hosting This Morning alongside his wife, Judy Finnigan, was one of 12 contestants taking part in this year's series at Gwrych Castle in North Wales.
Madeley has recently been one of several guest hosts for Good Morning Britain alongside Susanna Reid, following Piers Morgan's departure.
