Nancy Grace Disgusted by Photos of Casey Anthony Holding a Baby

Nancy Grace is repulsed by the pics of Casey Anthony holding a baby ... and pretty much just the sight of her in general.

Nancy tells us she was having a pretty good morning ... then she saw the photos of "Tot Mom" with a 6-month-old kid.

As we reported, Casey is holding the grandson of an NBC producer, who has been trying to snag an interview with her for a long time.

Nancy's especially upset there's alcohol at the table.
