Phillip Schofield has tested positive for Covid and has been forced to self-isolate.
The presenter, who fronts This Morning Monday to Wednesday, and Dancing On Ice alongside co-star Holly Willoughby, on a Sunday.
He posted the results of his lateral flow test on Instagram, writing: "Well b******s.
The TV star added: "Currently just a slightly sore throat".
It's likely he will now be ruled out of hosting This Morning for at least five days and he will need two negative lateral flows tests to be able to return to Dancing On Ice on Sunday.
Holly has also been absent from This Morning recently.
Phillip has been joined by presenter Rochelle Humes on the ITV daytime show, in place of Holly.
In a recent episode, as the programme opened, Phillip and Rochelle sat side-by-side and interviewed a viral internet skater before explaining Holly's whereabouts.
After the initial interview, Phillip turned to the camera and said: “Rochelle is here, as you can see. Keeping Holly’s seat warm. She’s off with the Ice Man, making a show at the moment.”
“Can’t wait to hang out,” said Rochelle. “Keeping her seat warm.”
Holly was given two weeks off the show - so she can present Wim Hof’s Superstar Survival alongside comedian Lee Mack.
Superstar Survival will see a whole host of famous faces take on Europe's harshest conditions in a bid to tackle their demons.
Holly will fly back to the UK at the weekends to film Dancing On Ice alongside Phillip.
A source told The Sun of Holly’s decision to take a break from This Morning: "Holly loved I’m a Celeb so much it gave her the confidence to strike out on her own and do more mainstream solo TV projects.
"Holly did an excellent job filling in for Ant and was one of the highlights of the show that year.
"She has high career ambitions and is starting the year as she means to go on."
The insider added: "However, she absolutely loves This Morning and her on-screen partnership with Phillip, so isn’t going anywhere long-term. She’s just grateful ITV bosses are giving her the freedom to do her own projects."
