Actor and singer David Cassidy is in a critical condition with organ failure, US media is reporting.
Cassidy, 67, who rose to fame in the 1970s television program The Partridge Family, was being treated at a Fort Lauderdale, Florida hospital, his publicist Jo-Ann Geffen told CNN on Saturday.
"He is conscious and surrounded by family and friends, nothing is imminent and we are taking it day by day," Geffen said.
The former teen heart throb was rushed to hospital three days ago and requires a liver transplant following a tumultuous few years.
He is also said to be suffering from kidney failure, a source confirmed.
Cassidy told People magazine in February he had has been suffering from dementia.
He said his grandfather and mother had also suffered from the disease and that he had decided to stop touring as a musician to concentrate on his health and happiness.
"I want to focus on what I am, who I am and how I've been without any distractions," he said.
"I want to love. I want to enjoy life."
The news of his dementia came days after Cassidy struggled to remember song lyrics at a performance in California.
He has had a turbulent personal life in recent years, including divorcing his third wife in 2014, filing for bankruptcy and being charged with drink-driving three times between 2010 and 2014.
