Russell Watson critically ill in hospital
The 40-year-old tenor, who has sold more than four million albums, was taken ill during a recording session on Thursday and is currently at the Alexandra private hospital in Cheshire.
A spokeswoman at the hospital confirmed that Watson was admitted yesterday afternoon, saying: "Russell Watson is at the Alexandra Hospital. He came in yesterday afternoon. No other information can be given at this time."
Last year Watson had a benign brain tumour removed, forcing him to cancel television appearances and delay his UK tour, but he recovered.
The singer's agent, Richard Thompson, said: "Our thoughts are with Russell and his family."
