#David Cassidy, teen heart-throb from the 1970s has died in hospital. Variety reported the 67-year-old "had been hospitalized for several days with organ failure." CNN reported that the star of "#The Partridge Family," had passed away and the news was confirmed by his publicist Jo-Ann Geffen.

David Cassidy first became known to his fans for playing the role of Keith Partridge in the TV series "The Partridge Family," when he was 16-years-old. The show ran until 1974.

In his music career, David Cassidy got a huge audience for his music, with his 1970s hit, "I think I Love You," rocketing him to fame. He had a fan club bigger than that of Elvis Presley.

Nevertheless, he struggled to cope with his fame and the hero-worship. He had to eventually go to rehab through alcohol abuse. [VIDEO]

More recently he was diagnosed with early dementia. He also suffered terrible pain from arthritis. The family said after he died that at least he was pain-free now.

Cassidy always hoped that his 1972 concert in Madison Square Garden would remain in the hearts of his fans forever. He also felt that having his family there was the "highlight" of his life.

Well, it seems that his music and his acting ability did stay in the hearts of his fans. More than thirty years later they took to Twitter to remember him and his achievements.
