Joni Mitchell was hospitalized Tuesday in Los Angeles, according to her website.
"Joni was found unconscious in her home this afternoon. She is currently in intensive care undergoing tests and is awake and in good spirits," a statement said.
It's unclear what caused her to become unconscious. The latest update on her website says they're awaiting word on her condition.
The 71-year-old singer-songwriter revealed last year to Billboard that she has a rare skin condition, called Morgellons disease, which prevents her from touring.
The eight-time Grammy winner is the voice behind such songs as "River," "Both Sides Now," "Woodstock," "Chelsea Morning" and "Big Yellow Taxi." She was inducted into the Rock and Roll Hall of Fame in 1997.
Last year, Mitchell released four-disc box set. Her most recent studio album, "Shine," came out in 2007. She recently attended Clive Davis' pre-Grammy bash in Los Angeles.
