DAVID CASSIDY Thrust into the spotlight at an early age, Cassidy \u2014 who played lead singer Keith on the '70s show \u2014 became an instant heartthrob and teen idol. Following the success of the original songs featured on\u00a0The Partridge Family, Cassidy, now 66, began recording his own music and ultimately launched a solo career \u2014 and produced five albums \u2014 while on the show. In recent years, the actor-musician\u00a0struggled in his personal life. In November 2010, he was charged with a DUI and was subsequently charged with the same offense in August 2013 and January 2014. A month after his third arrest, his wife, Sue Shifrin-Cassidy, filed for divorce. In February 2015, the actor filed for bankruptcy and was charged following his hit-and-run eight months later in October 2015. The '70s teen heartthrob and father-of-two, who was most recently seen on TV in a 2013 episode of\u00a0CSI: Crime Scene Investigation, has also battled substance abuse issues, including a stint in rehab in 2014.\u00a0In 2017,\u00a0Cassidy revealed to PEOPLE\u00a0that he had been diagnosed with dementia, a disease his grandfather and mother also battled. "I was in denial, but a part of me always knew this was coming," Cassidy said of his diagnosis.

SHIRLEY JONES Jones was the\u00a0matriarch of\u00a0The Partridge Family\u00a0clan, taking on the role of widowed mother-of-five Shirley Renfrew Partridge. Before starring on the hit show alongside her real-life stepson, David Cassidy, Jones, now 82 \u2014 who had a musical background \u2014 garnered critical acclaim and an Oscar for her Best Supporting Actress performance in\u00a0Elmer Gantry. Reflecting back on her time on\u00a0The Partridge Family, Jones is quick to issue a\u00a0caveat about starring on a hit show. "When my agents came to me and presented it to me, they said if you do a series and it becomes a hit show, you will be that character for the rest of your life and your film career will go into the toilet, which is what happened," she\u00a0said in a 2009 interview. "But I have no regrets." The star, who remarried in 1977 after her split from Jack Cassidy in 1974 (the pair had three sons together) continues to act. As for whether or not she's similar to her\u00a0Partridge Family\u00a0character,\u00a0Jones told the AP: "I am nowhere near as breezy and uncomplicated as Mrs. Partridge."

However, his professional life\u00a0\u2014 which also includes a\u00a0longstanding career\u00a0as a radio talk show host\u00a0\u2014 was overshadowed by his personal life, which included battles with drug addiction and alcoholism.
