As one of the presenters delivered a piece to camera, Grimmy was heard saying: “I’ve got shit all on my coat!”
The gaff went largely unnoticed apart from a few eagle-eared viewers who tweeted about it.
After one tweeted Grimmy to ask if he’d got the shit out of his coat, he replied: “Haha didn’t realise the old microphone would pick that up.”
Grimmy fans will get to see more of him on their screens in the coming weeks, as he is one of the stars who will appear in the new series of The Great Celebrity Bake Off for Stand Up To Cancer.
He recently revealed he’s also started writing a book during the pandemic, which will chart some of his most hilarious celebrity stories.
