Legendary funny lady Joan Rivers has been in a medically induced coma since Thursday, when she went into cardiac and respiratory arrest during a routine procedure at a doctor's office. Now, TMZ reports that she has been put on life support as her family keeps vigil at Manhattan's Mount Sinai Hospital. In a statement on Thursday, daughter Melissa Rivers said that her mother is "resting comfortably" and asked that people keep her in their thoughts and prayers. The most recent statement released through Mount Sinai on Sunday afternoon also had no update on her condition. In it, however, Melissa said, “We are keeping our fingers crossed.” So are we.
