NEW YORK -- Comedian Joan Rivers remained in serious condition in a New York City hospital Friday, one day after going into cardiac arrest at a doctor's office.
Melissa Rivers said in a statement Friday that her mother was "receiving the best treatment and care possible." She thanked Rivers' fans and friends for their support.
The host of "Fashion Police" on E! network, Joan Rivers also presides over an online talk show, "In Bed With Joan" and co-stars with her daughter on the WEtv reality show, "Joan & Melissa: Joan Knows Best?"
Her latest book, "Diary of a Mad Diva," was released this summer.
In 2009, Rivers emerged as the winner of NBC's "The Celebrity Apprentice." A documentary, "Joan Rivers: A Piece of Work," premiered in theaters in 2010.
The New York native originally entered show business with the dream of a theatrical career, but comedy became a way to pay the bills while she auditioned for acting roles.
"Somebody said, 'You can make six dollars standing up in a club,'" she told The Associated Press in 2013, "and I said, 'Here I go!' It was better than typing all day."
After proving herself in comedy clubs as a rarity -- a woman comedian -- Rivers was a smash on her first booking on "The Tonight Show Starring Johnny Carson" in 1965. "God, you're funny," Carson told her.
