She should just quit... Jessica Simpson has made a name for herself in the designing department. Her clothing/perfume/shoes/purses empire made like 1 billion dollars last year.
She should only come back if she's going to get some serious vocal training. She has so much potential, her voice is incredibly powerful, but she just doesn't know how to utilize it effectively. Such a shame because she could really be a premier vocalist. Some of the notes she can hit are just crazy.
