Joan Rivers Still Hospitalized, Daughter Melissa Rivers Shares New Statement and Fashion Police Co-Stars Call For Prayers

Update: The 81-year-old comedienne and host of the hit E! show remains in serious condition in a New York hospital after suffering complications from throat surgery

 Joan Rivers' daughter Melissa Rivers continues to thank people for their support as her 81-year-old mother remains in serious condition in a New York hospital, where she was taken after suffering complications from throat surgery.

The comedienne and host of E!'s Fashion Police was hospitalized on Thursday, just ahead of Labor Day Weekend, after she stopped breathing while undergoing a minor endoscopic procedure in a nearby clinic. She was placed in a medically induced coma. Her condition remains serious. Scores of fans and celebrities, including Joan's show colleagues and fellow standup comedians, have expressed well wishes.

"Thank you for your continued love and support," Melissa said in a statement on Sunday. "We are keeping our fingers crossed."

Joan's Fashion Police co-stars George Kotsiopoulos, Kelly Osbourne and Giuliana Rancic have all expressed their shock and well wishes for their friend and colleague.

"Social media has really just been very supportive and I think that is important right now if we collectively we all just pray for Joan to be well and back and laughing with us very soon," Kotsiopoulos told E! News exclusively. "Melissa and Cooper need you. We all need you. The world needs you."

Melissa, who is Joan's only child and has worked with her for years, and her 13-year-old son Cooper had flown to New York immediately to be by the comedienne's side at the hospital on Thursday.

Osbourne and Rancic shared moving messages, calling for prayers, on Twitter. Check them out below.
