Punk-rock legend Lou Reed died on Sunday on Long Island at 71-years-old after an undisclosed cause, Rolling Stone wrote. His passing ignited Twitter, with thousands of fans and admirers taking to the social-media site to pay homage to the music star. The influential songwriter is best known for his hits like "Rock & Roll," "Sweet Jane" and "Walk on the Wild Side.”

The rocker had reportedly undergone a liver transplant in May and had hoped to recover. The founder of the Velvet Underground was fondly remembered on the social-media site, with many using puns from titles of some of his greatest hits, and others saying they were sad to see him go.

Reed continued to make music throughout his life and most recently released an album in 2011, “Lulu,” a collaboration with the hard rock band Metallica. In 1987 he told Rolling Stone every record he made was like a chapter of his life.

“All through this, I’ve always thought that if you thought of all of it as a book then you have the Great American Novel, every record as a chapter,” he said. “They’re all in chronological order. You take the whole thing, stack it and listen to it in order, there’s my Great American Novel.”

Hollywood was also affected by Reed’s passing, and some shared their sympathies on Sunday. Check out some of their posts below:
