"Partridge Family" star David Cassidy is suffering from multiple organ failure at a Florida hospital, his rep confirmed to several media outlets Saturday.
Cassidy, 67, was admitted to the unidentified facility earlier this week.
A spokesperson told the New York Post that Cassidy was "conscious" and "surrounded by family." His hospitalization was first reported by TMZ.
Publicist JoAnn Geffen said Cassidy was in a Fort Lauderdale-area facility with liver and kidney failure. She said he's in a private room, conscious and surrounded by family.
Geffen added that there was nothing "imminent" about Cassidy's condition, and doctors were hoping to "keep him as well as they can until they can find another liver."
The New York Daily News, citing Cassidy's rep, reported that the singer's liver and kidney were failing and he needed a transplant.
In February, Cassidy revealed to People magazine that he was battling dementia after he struggled to remember song lyrics and fell off the stage at a show in California.
"I was in denial, but a part of me always knew this was coming," Cassidy said at the time. "I want to focus on what I am, who I am and how I’ve been without any distractions."
Cassidy has also battled substance abuse issues and went to rehab in 2014.
Cassidy's father was actor Jack Cassidy, who died in 1976. His mother was actress Evelyn Ward, who died in 2012.
Shirley Jones, 83, who played Cassidy's mother on "The Partridge Family," was Jack Cassidy's second wife and David Cassidy's stepmother.
