David Cassidy is hospitalized with critical organ failure as doctors warn he desperately needs liver transplant - or he could die.

The family of the singer have reportedly been told to 'expect the worst'

David Cassidy is in a critical condition with organ failure after months of ill health.

The actor and singer, 67, had been put in a medically induced coma since being taken to a Florida hospital three days ago.

However, Cassidy's representative has told me "He is currently conscious surrounded by family."

She confirmed that he is suffering from kidney failure and is in a desperate need of a liver transplant.

"I don't know what his condition is technically but he is quite ill," she added.

The Partridge Family star opened up about his dementia diagnosis in February this year, after worried fans questioned his health following a gig in which he forgot the lyrics to his own songs.

"I was in denial, but a part of me always knew this was coming," he said at the time.

David revealed his grandfather and his mother both battled the disease, and speaking to People magazine about his mom's struggles, he continued: "In the end, the only way I knew she recognized me is with one single tear that would drop from her eye every time I walked into the room… I feared I would end up that way."

The Partridge Family star told the magazine that he planned to stop touring this year to concentrate on his health.

I want to focus on what I am, who I am and how I've been without any distractions. I want to love. I want to enjoy life," he added.

The former teen heartthrob had been performing at the Canyon Club in Agoura and appeared to forget the lyrics at times.

He also took a tumble during one song as he was playing an instrumental break with his keyboard player, staggering off the edge of the stage.

And later on he stopped playing guitar and handed it to a technician as he complained: "Apologies, I can't play the guitar this badly out of tune."

As he went to take the microphone off the stand, he pulled it back and hit himself in the face with it.

"Obviously you're not listening, so it doesn't matter. I'll just shut up now," he also said after one fan shouted out while he was talking.

In recent years, the former teenage pin-up has hit headlines for his alcohol problem and run-ins with the law, including being arrested twice for driving under the influence.

In 2015 he appeared on This Morning to discuss his decision to file for bankruptcy in an interview branded incredibly awkward.

Just last month he was evacuated from his home in Florida after Hurricane Irma hit the state causing widespread flooding that affected hundreds of thousands of residents.

And a few days before that he was able to answer fans' questions on his official website.

In answer to queries about his health, he replied: "I am doing well. I am keeping busy. Of course, I have good days and some not so good. Don't we all? I am 67 years old!"

He also said his last album, Songs My Father Taught Me, would be finished shortly.

"The songs should be finished by the end of the year," he confirmed.

"I hope you enjoy them as much as I do. I have had so much fun recording them with my band. They are so talented."

David added that he continues to play the guitar every day as he finds it the best way to relax.

Earlier his year, he vowed that the album - a tribute to his late dad Jack Cassidy - would be his last.

"People may respond that it's just worship of my male role model, especially as he basically abandoned me and my mother. I truly believe he was the most talented man I've ever known. Soooooooo, I'm going to go in and pay tribute to him with "Songs my father taught me"," he told his fans on Facebook.

"I truly believe this will be my last recording, and it's been something I've been thinking about for many years."
