Jeremy Clarkson has been rushed to hospital with severe pneumonia.
The 'Grand Tour' star became unwell while on a trip to Majorca with friends and was admitted to hospital while he recovers.
A spokeswoman for The Grand Tour said: "Jeremy Clarkson was admitted to hospital on Friday morning during a family holiday in Spain, and is being treated for pneumonia."
And friends are concerned that he needs to start taking better care of his health.
A source told The Sun on Sunday: "He's told friends not to expect to hear too much from him over the next few weeks which is very unlike him, and obviously his family are concerned.
"Inevitably people close to him are saying it's time to think about the way he looks after himself - cutting back on the booze and fags - but he's never been one to take that sort of guidance on board."
Jeremy, 57, previously revealed that he suffered a cancer scare in 2015, two days before he assaulted a BBC 'Top Gear' producer.
He said: "Two days before the 'fracas', I had been told, sternly, by my doctor that the lump on my tongue was probably cancer and that I must get it checked out immediately. But I couldn't do that.
"We were in the middle of a 'Top Gear' series. And 'Top Gear' always came first.
"That was the most stressful day I have ever had in 27 years at the BBC.
"It was beyond-belief stressful, everything was going wrong, and then you know... there you go. But everyone has stressful days, and they manage to cope better than I had."
