Ant McPartlin and Declan Donnelly have pulled out of work engagements after falling ill.
The pair, who are gearing up to host another series of I’m A Celebrity, reportedly have a ‘sudden’ illness, which has forced them to scrap an appearance on a Britain’s Got Talent special.
They will be replaced on BGT by former Britain’s Got More Talent host Stephen Mulhern, an ITV spokesperson said.
There is also now a question mark over whether they will attend tomorrow’s National Television Awards.
