Joni Mitchell hospitalized

'Big Yellow Taxi' singer in intensive care

Joni Mitchell's famous fans are voicing their support and worry for the folk song icon while she is hospitalized in Los Angeles.

"Harry Potter" star Emma Watson said Wednesday on Twitter: "heard about Joni and haven't been able to concentrate all morning. So hope she's doing ok."

Kiss lead singer Paul Stanley tweeted a recent picture of himself and the Rock and Roll Hall of Famer, telling his followers to send her love and prayers.

Kevin Bacon tweeted that he was "sending good wishes today to one of the finest singing, song-writing, guitar playing artists in history."

Boy George, Bill Idol and Tori Amos were also among the well-wishers.

FOX NEWS HEALTH: What is Morgellons disease?

Mitchell, 71, was found unconscious in her home Tuesday night and taken to a hospital by ambulance, according to her Twitter account and website. She was later in intensive care and undergoing tests.

Her representatives did not immediately respond to phone and email messages and there was no further word on her condition Wednesday.

Mitchell told Billboard magazine last year that she has a rare skin condition, Morgellons disease, which prevents her from performing.

There is much debate about Morgellons disease and its origin, with the Centers for Disease Control and Prevention (CDC), which refers to it as unexplained dermopathy, struggling to categorize it.

Sufferers complain of sensations of crawling bugs and fibrous material or solid objects embedded in the skin and non-healing lesions. Some patients report fatigue, memory loss and a substantial decline in quality of life. A 2012 report from the CDC which was published in PLoS ONE found that the condition is not contagious; eliminating the possibility that it has an infectious cause.

A native Canadian who became part of Southern California's flourishing folk-rock scene in the 1960s, Mitchell has won eight Grammy Awards, including a lifetime achievement award in 2002. She was inducted into the Rock and Roll Hall of Fame in 1997.
