Joan River's Celebrity Doctor -- I Didn't Know They Were Taking Selfies

The doctor who went down Joan Rivers' throat as the comedian slipped away says she had no idea another doctor was taking selfies during the procedure.

Dr. Gwen Korovin has filed legal docs answering claims in the wrongful death lawsuit, denying that she's responsible for Joan's death.  The selfies -- taken by another doctor -- are evidence of unprofessionalism that led to Joan's death, according to the suit.

The lawsuit makes a number of claims, including Dr. Korovin was not even authorized to practice at the clinic, and that she fled the room once an emergency was declared.  Korovin says in her response she was invited to perform the procedure.

As for the photos, according to the lawsuit, another doctor said he was taking the pics to show them to Joan in the recovery room.
