Simon Cowell worried Celebrity X Factor viewers as they feared he was ill tonight.
The 60-year-old appeared on the ITV show this evening as a batch of celebrities hoped to wow with their vocals.
However his dramatic weight loss, a result of his vegan diet, distracted fans tonight as he looked almost like a different person.
One tweeted: “Is Simon Cowell okay? Really doesn’t look well! #XFactorCelebrity.”
Another wrote: “Is Simon Cowell ill? He looks awful – really gaunt, scrawny and unhealthy. #XFactorCelebrity #SimonCowell.”
A third remarked: “#XFactorCelebrity Simon looks so ill.”
“Simon Cowell – what’s going on? He looks ill and sounds terrible. Hope he’s ok #XFactorCelebrity,” another wrote.
A fan commented: “#XFactorCelebrity Simon cowell looks ill, and slurred.”
One wrote: “Simon looks seriously ill #XFactorCelebrity.”
Another worried: “Is Simon Cowell ill? He looks absolutely awful. #XFactorCelebrity.”
