I must admit that I had never heard of Ms. Stewart until she became famous for her legal problems. She had some claim to fame before, but it has been eclipsed. As I said in the comment, "convicted felon" is the accurate legal term for what she is, and it is a big part of her current notoriety.  There is no personal attack in calling someone by what the courts have deemed her to be. However, hiding her legal status is exceedingly POV. I think you have to admit that this is true.
