The American comedian was taken to hospital with burns to his face after what his spokesman described as a ‘flash fire’. The 72-year-old former Tonight Show host canceled a Las Vegas show scheduled for Sunday night after suffering a “very serious medical emergency,” People magazine reported. “I got some serious burns from a petrol fire. I’m fine. I just need a week or two to get back on my feet,” he said in a statement to Sky News partner NBC News. According to Reuters, Leno was taken to Grossman Burn Center for treatment, but his eye and ear were not seriously damaged. Since leaving the Tonight Show in 2014, the avid car collector, who owns more than 200 vehicles, has hosted a revival of popular US game show You Bet Your Life as well as Jay Leno’s Garage on CNBC. He also writes a regular column in Popular Mechanics magazine, showcasing his collection and giving automotive advice.
