Ant McPartlin chopped off the tip of his thumb as he prepared a Sunday dinner for his sidekick Declan Donnelly, the Sun reports.
The presenter was working out how to use a vegetable-slicer when the accident occurred, as he was planning to make dauphinoise potatoes the next day. He told the Sun:
"It was a complete disaster. I ended up slicing the top of my thumb off. God, it was painful. It hurt like hell. There was a lot of blood."
The star rushed to hospital, hoping that the tip could be stitched back on, but medics were only able to clean and dress the injury. Despite his ordeal, he managed to cook a roast for his friend and business partner the next day.
