Music legend Joni Mitchell is still hospitalized but is "doing better," her spokeswoman told The Los Angeles Times on Wednesday.
The singer-songwriter was taken to a Los Angeles hospital after being found unconscious at her home in Bel Air Tuesday, according to her official website.
Mitchell, 71, is said to have regained consciousness soon after, and is receiving treatment for an unknown ailment. The spokeswoman told LA Times, Mitchell is undergoing tests to determine the cause of the incident.
A statement on her website, which is not run by the singer, said: "Joni was found unconscious in her home this afternoon. She regained consciousness on the ambulance ride to an L.A. area hospital.
"She is currently in intensive care undergoing tests and is awake and in good spirits. More updates to come as we hear them. Light a candle and sing a song, let's all send good wishes her way."
A Los Angeles Fire Department spokesman confirmed they had attended her residence, but would not reveal the identity of the individual who received treatment.
NBC4 contacted Mitchell's representatives for comment, but has yet to receive a response.
The phrase "Joni Mitchell please be okay" was trending on Twitter Wednesday, while musical titans such as Boy George, Billy Idol and LeAnn Rimes also tweeted messages of support.
In December it emerged she is no longer able to perform as she is suffering from rare skin condition, Morgellons disease.
"I can't sing any more - don't miss it. I can't play any more - don't miss it. I've got all these instruments laying around and hopefully one day I'll pick them up," she told Billboard.
Morgellons is a condition in which thread-like fibers appear under the skin, and patients often complain of feeling crawling or stinging all over.
But while some medical experts say it is a physical illness, others suggest it is a type of psychosis.

Her best known songs include 70s classics "Big Yellow Taxi" and "Woodstock," while her 1971 recording Blue is rated the 30th best album ever made by Rolling Stone magazine.
