One-time teen idol David Cassidy has faced some tough times recently, ranging from financial struggles to DUI arrests to a stint in rehab late last year, and it appears that the troubles are not over for the former star of “The Partridge Family”.

In footage obtained by TMZ of a Los Angeles-area concert on Saturday night, the “I Think I Love You” singer is seen slurring his words, forgetting lyrics and, at one point, falls backwards off the stage, making some wonder whether Cassidy has fallen off the wagon after entering rehab in October 2016.

During the shambolic show, Cassidy, 66, reportedly told fans that his Sunday night show would be his last ever, due to health reasons.

In a Feb. 3 blog post on his official website, Cassidy announced that he’s planning to retire at the end of 2017, writing: “This has been a very difficult decision for me that nobody can possibly understand.” In a subsequent post, he writes: “I’m not going to vanish or disappear forever,” and adds, ” I’m going to play live, everywhere around North America, through 2017.”

Meanwhile, The National Enquirer is reporting that Cassidy is wrapping up his bankruptcy, claiming that he earns approximately $12,500 per month while “his debts are more than twice that amount!”

According to court documents obtained by the Enquirer, Cassidy is “proposing this plan of reorganization primarily to resolve pending litigation which arose during a very stressful and challenging period of his otherwise successful career.”

The documents also state: “While he still loves performing for his fans, it is more difficult to travel … due to his health.”

TMZ has reached out to a rep for Cassidy but has yet to receive a response.
