Joan Rivers: Celebrities Mourn the Death of the Comedian on Twitter

Fashion Police host, Joan Rivers, died today aged 81, her daughter has confirmed.

"She passed peacefully at 1:17 p.m. surrounded by family and close friends. My son and I would like to thank the doctors, nurses, and staff of Mount Sinai Hospital for the amazing care they provided for my mother," said her daughter, Melissa Rivers in a statement to ABC News.

Joan was admitted to the Mount Sinai Hospital last Thursday, where it was determined that she had suffered cardiac arrest and a subsequent stroke.

She was later placed on life support.

Celebrities have poured in condolences on Twitter following the news.
