Iconic singer Joni Mitchell is currently in hospital after an emergency call took responders to her Los Angeles home after having allegedly collapsed.

According to TMZ, someone called 911 on Tuesday, saying they had found a woman unconscious. Sources speaking with TMZ said paramedics were called at 2:30 p.m. When Mitchell was transported to the hospital she was alert.

However, according to TMZ sources and also Joni Mitchell’s official Twitter account, the 71-year-old singer was placed in the intensive care unit. She had surgery after arriving.

In another tweet a couple hours later, it was revealed the singer remains in the ICU but is “in good spirits.”

Mitchell is one of the most iconic singers to come out of the Lauren Canyon era, according to the Los Angeles Times. Some of her best known songs are “Big Yellow Taxi,” "Free Man in Paris" and “Help Me.” She was integrated into the Rock and Roll Hall of Fame in 1997.

"I have a tremendous will to live," she told the Los Angeles Times in 2010 and says she has Morgellons, a controversial disease.

It is an “unexplained skin disorder characterized by sores, crawling sensations on and under the skin, and fiber-like filaments emerging from the sores. It's not certain what these strings are. Some say they are wisps of cotton thread, probably coming from clothing or bandages. Others say they result from an infectious process in the skin cells,” according to the Mayo Clinic.

“I'm a polio survivor, so I know how conservative the medical body can be," she told the Los Angeles Times. "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."
