Comedienne Joan Rivers is still hospitalized, and her daughter Melissa Rivers issued a statement yesterday: "Thank you for your continued love and support. We are keeping our fingers crossed."

Rivers went into cardiac arrest during a surgical procedure on Thursday. She has reportedly been placed in a medically-induced coma at Mount Sinai Hospital, and some reports say she's on life support.

Her former writing partner, Jay Redack, told the Post that she had discussed the surgery on Wednesday: "She said her throat was bothering her for a long time. Her voice was getting more raspy, if that was possible. She said she was just going in for a little procedure in the morning, that was it... What’s ironic is at dinner [Wednesday night], we were talking about who goes first. I’ve know Joan so damn long. I said, ‘Here’s what I’ll leave you if I go first. What’ll you leave me?’ She said, ‘I’ll think about it."

According to the Daily News, Rivers is undergoing a "wake-up process" from the coma, but a source said, "There is real concern that the part of the brain that controls motor skills may have been compromised, leaving her as either a vegetable or in a wheelchair." The source added that the family might sue Yorkville Endoscopy, where Rivers was having the initial procedure: "Shock and upset is turning to anger, and they are looking for someone to blame... An 81-year-old should not have that procedure as an outpatient. Very ill advised."

Rivers' Fashion Police co-star George Kotsiopoulos told E!, "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." He then mentioned her daughter and grandson: "Melissa and Cooper need you. We all need you. The world needs you."
