After a performance Saturday night in L.A., DAVID CASSIDY revealed he's battling DEMENTIA. He told "People" magazine that his grandfather and his mother had it, and, quote, "I was in denial, but a part of me always knew this was coming."

Cassidy is 66, and he is going to stop touring to concentrate on what's important. He said, quote, "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." Support from his fans and fellow musicians poured in all over social media yesterday. I was a HUGE Partridge Family fan, and wish him good health, happiness, and most importantly peace.
