Hollywood Remembers 'Fabulous,’ ‘Hysterical’ Joan Rivers

E! castmates, Lena Dunham, Demi Lovato, Ariana Grande and more remember the legendary comic.

We lost Joan Rivers on Thursday (September 4), and the world became a little less funny.

The legendary comic and host of E!'s "Fashion Police" died after being taken off life support following complications while undergoing a recent throat operation in New York City. She was 81 years old.

“She passed peacefully at 1:17 p.m. surrounded by family and close friends,” her daughter, Melissa, said in a statement. “My mother’s greatest joy in life was to make people laugh. Although that is difficult to do right now, I know her final wish would be that we return to laughing soon.”

Joan was not only a comedic genius but a pioneer as well, becoming the first female to host a late-night talk show in 1986. Since then, she had pretty much conquered everything that show business has to offer. She had her own daytime talk show, a reality TV series, she was an author and continued to do stand-up.

Friends, family, comedians and colleagues all took to social media to pay their respects and memories for Joan as the news of her passing spread. Her network family at E! released a statement declining to address the fate of her hit style series, saying, “Right now we are mourning our beloved Joan. We will respond at a later date with programming updates.”
