NEW YORK (AP) -- Comedian Joan Rivers is in a New York City hospital, according to police and hospital officials who say she was rushed there from a doctor's office after going into cardiac arrest.
There's no word on the condition of the 81-year-old.
A spokesman at The Mount Sinai Hospital says there will be an update on her condition "as soon as it becomes available." He says Rivers' family "wants to thank everybody for their outpouring of love and support."
Rivers has spent a half-century in show business. She was a pioneer of red-carpet commentary -- and the snarky criticism that often accompanies it. Her signature question has been, "Who are you wearing?" She continues to maintain a busy schedule, and was supposed to perform a show tomorrow night in New Jersey. It has now been postponed.
Just last night, she spoke at an employee event at Time Inc. in New York. An employee there says Rivers "seemed totally healthy," and was "very energetic."
Rivers is host of "Fashion Police" on E! Network, and co-stars with her daughter, Melissa, on a WEtv reality show. She also presides over an online talk show.
After proving herself in comedy clubs in the 1960s, Rivers was a smash on her first booking on "The Tonight Show" in 1965, and went on to become a regular guest and then a guest-host before getting her own talk show.
