What's that old saying: there is no such thing as bad publicity
I can't fault her for using her fame (infamy) to play the system. Here is a TMZ page on her. She made $28k in June.

I suspect the publicity will help her ride the wave.
If I hadn't seen her on Oprah I would wonder why she has not been able to capitalize on her children like Kate and whatever her husband is/was and their brood. Suleman is simply a really weird person.
