I have seen the same movie (or one similar). If I remember correctly, the TV show wanted to have her get all kinds of plastic surgery and stuff, and the fine print on her contract was that if she broke the deal she'd have to pay them... so she read the fine print and realized they would terminate the contract if she did anything to hurt the show's rep, so that's why she shoplifted.
I couldn't remember the title either, tried a google search, then tried searching IMDB quotes for "Goodheart" and found it:
The Story Lady. It was made-for-TV, so it is pretty obscure.
