Jessica Simpson is reportedly in trouble with Weight Watchers.  A source is saying that execs are livid that their new spokeswoman because she got pregnant seven months after giving birth to her baby girl, Maxwell.  She has a $4 million deal with Weight Watchers. She was already on thin ice with the company because they had to shoot her first set of commercials from the waist up because she hadn't lost enough weight by that point.  Unfortunately, Jessica's second WW campaign -- celebrating a 70-pound loss -- may not air. "They don't think it can run," a source explains. "No one wants to hear about a pregnant woman dieting."
