The family of Joan Rivers has thanked everyone for the "outpouring of love and support" after the comedian was reported to be in a "critical condition" in hospital.
An update on the 81-year-old star's condition will be provided "as it becomes available", spokesman Sid Dinsay for the Mount Sinai Hospital in New York said.
In a statement issued last night he said: "This morning Joan Rivers was taken to the Mount Sinai Hospital in New York, where she is being attended to.
"Her family wants to thank everybody for their outpouring of love and support. We will provide an update on her condition as it becomes available."
Earlier, a spokesman for the NYPD said: "An 81-year-old is in a critical condition at Mount Sinai Hospital."
He was unable to confirm reports on the TMZ website that her heart had stopped beating at one point. The US site reported that Rivers was undergoing a throat procedure in a clinic when she became unwell but the spokesman could not confirm this.
