(CNN) "Star Wars" fans and the entertainment world lost Hollywood royalty when actress Carrie Fisher died on Tuesday. She was 60.

The actress, best known for playing Princess Leia Organa in the massively popular space saga, died four days after suffering a cardiac event on a flight from London.

Fisher's co-stars and others in Hollywood, joined by legions of heartbroken fans, took to social media Tuesday to pay tribute to a woman who played one of the most iconic roles in movie history, and then went on to achieve much more.
