Former teen idol David Cassidy is in hospital after reportedly suffering organ failure.
The US actor and singer, 67, is “conscious and surrounded by family” after being rushed to hospital in Florida earlier this week, his spokeswoman said.
He had been in an induced coma following kidney failure and needs a liver transplant, according to reports.
Cassidy revealed earlier this year he was battling dementia after video emerged of him performing erratically in California.
He forgot the words to some of his own songs and yelled at a fan to turn off a light that he claimed was blinding him.
Cassidy later told People magazine he had been in “denial” about his illness and he had decided to stop touring, saying he wanted to “enjoy life”.
Cassidy shot to fame in the 1970s as Keith Partridge in TV sitcom The Partridge Family, starring opposite his stepmother Shirley Jones.
He went on to enjoy a hugely successful pop career and scored two UK number ones with How Can I Be Sure and Daydreamer.
But in recent years he has struggled with alcohol problems.
Cassidy was arrested three times for drink driving between 2010 and 2014, and was ordered to go to rehab as part of his sentence in 2014.
A month after his third arrest, his wife, Sue Shifrin-Cassidy, filed for divorce.
Cassidy, who has two children, had to auction off his Florida home in 2015 after filing for bankruptcy.
