American actress-comedienne Joan Rivers, who is reportedly on life support, became the victim of a celebrity death hoax.

According to TMZ, the 81-year-old, who is best known for co-hosting the E! celebrity fashion show Fashion Police, is now on life support to stay alive after suffering from a cardiac arrest during throat surgery.

The hashtag #RIPJoanRivers has been trending on Twitter after news spread of her condition.

Meanwhile, Joan's daughter, Melissa Rivers, recently released a statement about her mother's condition.

"My mother would be so touched by the tributes and prayers that we have received from around the world. Her condition remains serious, but she is receiving the best treatment and care possible. We ask that you continue to keep her in your thoughts as we pray for her recovery," the 47-year-old television personality said in a statement to E! News.
