Teenage heartthrobs run in the Cassidy family. David Cassidy's younger brother, Shaun Cassidy, who was also a teen idol and singer in the 1970s, remembered his late brother with a touching tribute on Twitter after the pop culture icon's death Tuesday from organ failure.

“When I was a little boy and my big brother would come to visit, the first call of business would be a punishing pillow fight. During the battle, he would regale me with hysterical stories of our father, often culminating in his taking a giant leap off my top bunk,” Cassidy posted on Twitter, along with a black and white photo of the boys as children.

“I tried to catch him of course. I always tried to catch him. But I never could. Now, I will carry him, along with all of the funny/sad/extraordinary days we shared, none more filled with love than these last few at his side.”

Eight years younger than David, Shaun was the oldest son of Jack Cassidy and Shirley Jones, while David was Jack’s only child with his first wife, Evelyn Ward. In addition to being his step-mother, Shirley Jones played David Cassidy’s on-screen mother in the ‘70s musical sit-com “The Partridge Family.”

The relationship between Cassidy and his family was strained over the past years over his battle with alcoholism. Several months before his death, a video of Cassidy struggling to perform at a live show raised concerns about his well-being. Family and fans thought he had relapsed, instead he revealed he was suffering from dementia.

Regardless of past estrangements, his family rushed to his side after hearing of his hospitalization. A source told People magazine, Cassidy "was delighted to see them … There's been total resolution within the family. They will always be there for him."

David Cassidy passed away in a Florida hospital on Nov. 21. at the age of 67.

An outpouring of tributes came from celebrities, including Danny Bonaduce — who played David's television brother — John Stamos, Marie Osmond and Carnie Wilson.

Cassidy is survived by half-brothers Shaun, Patrick and Ryan; daughter Katie Cassidy and son, actor Beau Cassidy.
