Joan Rivers greets the audience at the 'Comedy Central Roast of Joan Rivers' in 2009 in Los Angeles.

London - Joan Rivers' funeral will take place in New York this weekend.

The 81-year-old comedienne, who passed away on Thursday following surgical complications, will be laid to rest at Temple Emanu-El in Manhattan on Sunday, Us Weekly has confirmed.

Elizabeth Fezrine, a spokeswoman for the congregation, said details about the service - including the time and whether the public will be allowed to attend - are not yet known.

Joan's daughter Melissa announced on Thursday night her mother had died at lunch time following a week on life support at Mount Sinai hospital in New York.

Joan had been rushed via ambulance to the medical centre after she suffered a cardiac and respiratory arrest while undergoing a routine operation on her vocal cords at Yorkville Endoscopy clinic last Thursday.

The 'Fashion Police' host was placed in a medically-induced coma after the health scare, but showed signs of improvement on Wednesday when she was moved out of intensive care and into a private room at the hospital.

Yorkville Endoscopy clinic is now being investigated by the New York State Department of Health, spokesperson James O'Hara told CNN.

Meanwhile, Melissa, 46 - Joan's only child - has thanked fans for their continuous love and support.

She said in a statement: "Cooper [my son] and I have found ourselves humbled by the outpouring of love, support, and prayers we have received from around the world. They have been heard and appreciated."

Several celebrities took to social media to pay tribute to the legend.

Sharon wrote on her Twitter account: "We've lost a true legend today and an amazing woman - a pioneer. She opened up the arena for women in comedy.... (sic)."
