Hours before being rushed to the hospital on Thursday morning, Joan Rivers appeared before the LGBT community of New York City.

On Wednesday night, the comedian hosted a OUT@ Time Inc. event where she addressed 150 guests in honour of her new book “Diary of a Mad Diva.”

Conversation flowed about her life and career as Rivers engaged with People and Entertainment Weekly’s editorial director Jess Cagle for the special night.

Time Inc. staffers as well as members of the OUT@ Time Inc. community came out to the Time & Life building to hear a dose of the icon’s unapologetic comedic style.

Photos of last night’s appearance captured a smiling Rivers dressed in her signature style.
