The Partridge Family star was rushed to hospital in Florida last week after suffering from liver and kidney failure.
And the family of the 67-year-old has released a statement on his condition after a difficult week.
A message on the singer’s official Facebook page reads: “Unfortunately David is very sick. However he is getting the support he needs, surrounded by the people he loves most.
“Thank you very much for the love and concern that you have expressed in your messages to him,” David’s son, Beau Cassidy, wrote.
Meanwhile a source told Us Magazine: “He is hoping and waiting for a liver transplant. If he happens to get one on time the prognosis is up in the air.”
People magazine claim that on Saturday David Cassidy woke up surrounded by his family, including his son Beau Cassidy, ex-wife Sue Shifrin and his brother Patrick, after being in a coma.
“When his brother Patrick walked into the room, David lit up like a Christmas tree,” a source told the publication.
“There’s been total resolution within the family. They will always be there for him.”
This weekend, David was said to be in a critical condition in an induced coma.
TMZ claimed he “needed a liver transplant soon or he could die” and his family were told to “prepare for the worst”.
Earlier this year, David revealed his battle with dementia.
“I was in denial, but a part of me always knew this was coming,” the 67 year old told People. “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.”
