Legendary folk singer-songwriter Joni Mitchell was rushed to hospital after being found unconscious at her LA home.
The musician's official Twitter account confirmed the news, saying that she was in intensive care.
A spokesperson for the Los Angeles Fire Department confirmed that paramedics responded to an emergency 911 call on Mitchell's street in Bel Air at about 2.30pm on Tuesday, but was unable to confirm her condition.
Mitchell regained consciousness on the way to the hospital .
The Canadian-born singer told 'Billboard' magazine in December that she has a rare skin condition, Morgellons disease, which prevents her from performing. Still, she released a career-spanning four-disc box set last year and appeared at Clive Davis's annual pre-Grammy party in February.
Mitchell has received eight Grammy Awards, including a lifetime achievement award in 2002. She was inducted into the Rock and Roll Hall of Fame in 1997. She started her career as a street musician in her native Canada before moving to Southern California, where she became part of the flourishing folk scene in the late 1960s.
Her second album, 'Clouds', was a breakthrough with such songs as 'Both Sides Now' and 'Chelsea Morning', winning Mitchell the Grammy for best folk performance. Her 1970 album, 'Ladies of the Canyon', featured the hit single 'Big Yellow Taxi' and the era-defining 'Woodstock'. The following year, she released 'Blue', which ranks 30th on 'Rolling Stone' magazine's list of the '500 Greatest Albums of All Time'.
