Rivers was having throat surgery in New York when she stopped breathing and was rushed to Mount Sinai Hospital in New York in a critical condition.

Her daughter Melissa Rivers released a statement thanking everyone for their support.

“I want to thank everyone for the overwhelming love and support for my mother,” said the statement released through a Mount Sinai spokesperson.

“Her condition remains serious but she is receiving the best treatment and care possible.”

The Emmy-winning host of channel E! show Fashion Police has received well-wishes from famous friends like Ellen Degeneres on Twitter.
