Joni Mitchell "is awake and in good spirits" in intensive care after she was rushed to a Los Angeles hospital Tuesday upon being found unconscious in her Bel Air home.
According to a statement on the singer's Twitter account and website, the Rock and Roll Hall of Famer is "currently in intensive care undergoing tests" after officials said paramedics responded to a 911 call to her home around 2:30 pm PT Tuesday.
The latest update Tuesday declared: "Joni has been hospitalized. We are awaiting official word on her condition and will post it here as soon as we know."
Early Wednesday, it was not clear what condition caused the 71-year-old folk singer to fall ill, though she told Billboard magazine late last year that a skin condition called Morgellons disease had kept her sidelined from the stage.

She told the L.A. Times in 2010 of her health battles, "I have a tremendous will to live.
"I'm a polio survivor, so I know how conservative the medical body can be. In America, the Morgellons is always diagnosed as 'delusion of parasites,' and they send you to a psychiatrist. I'm actually trying to get out of the music business to battle for Morgellons sufferers to receive the credibility that's owed to them."
The eight-time Grammy winner, who was honored with the lifetime achievement award 13 years ago, is best known for songs such as "Big Yellow Taxi," "Woodstock," "Both Sides Now" and "Chelsea Morning."
