Johnny Cash is in hospital with pneumonia.
The country star is in a serious but stable condition at Baptist Hospital in Tennessee.
He was admitted to the hospital yesterday morning.
The 68-year-old was treated for pneumonia during a two-week hospital stay in October 1999.
In 1998 he was taken to hospital twice for the lung inflammation and said later he nearly died.
The Man in Black is known for songs like A Boy Named Sue, Folsom Prison Blues, I Walk The Line and Sunday Morning Coming Down.
An eight-time Grammy winner and a six-time winner of Country Music Association awards, Cash was elected to the Country Music Hall of Fame in 1980 and inducted into the Rock n Roll Hall of Fame in 1992.
He was nominated this year for two more Grammys.
