According to Us Weekly, WW execs are "livid that their new spokeswoman got pregnant just seven months after welcoming daughter Maxwell."

A source tells the mag, "They're furious at Jessica. She was already on thin ice with them since she didn't lose enough for a the first ad, when they had to shoot from the waist up."

As a result, Simpson's second campaign, in which she is celebrating a 70-pound loss, may not even air. "They don't think it can run," the source explains. "No one wants to hear about a pregnant woman dieting."

Uh oh! What next?
