Beach Boys founder Brian Wilson, singers Harry Connick Jr. and Gloria Gaynor, and Hollywood movie star Ben Stiller were among the dozens of famous faces who used Twitter to pay their respects to “The Partridge Family” star.
Cassidy’s longtime publicist, JoAnn Geffen, confirmed Cassidy’s death via a statement on Tuesday night. Cassidy, who’d struggled with alcohol abuse throughout his career, had been hospitalized over the weekend after reportedly suffering organ failure.
Fellow musicians and celebrities shared their condolences on Twitter, with many mourning the loss of their childhood idol:

I’m very sad to hear about David Cassidy. There were times in the mid-1970s when he would come over to my house and we even started writing a song together. He was a very talented and nice person. Love & Mercy to David and his family.— Brian Wilson (@BrianWilsonLive) November 22, 2017

Sad to learn David Cassidy has died. Like his father Jack he had great talent, and a complicated life. Condolences to his wonderful family.— Larry King (@kingsthings) November 22, 2017
I grew up in an era before even cable TV, when The Partridge Family was already in reruns. David Cassidy's Keith was one of my favorite TV characters. He was legit funny AND he could sing. The man entertained me during my childhood and even years later:https://t.co/678DU7qTxh— KevinSmith (@ThatKevinSmith) November 22, 2017
