Joan Rivers, the raucous, acid-tongued comedian who crashed the male-dominated realm of late-night talk shows and turned Hollywood red carpets into danger zones for badly dressed celebrities, died Thursday. She was 81.

Rivers was hospitalized last week after she went into cardiac arrest at a Manhattan doctor's office following a routine procedure. Daughter Melissa Rivers said she died at Mount Sinai Hospital in New York, surrounded by family and close friends. RIP Joan Rivers
