If in the public eye Jessica Seinfeld is merely a comely alleged plagiarist, to those closest to her, she's more like the Soup Nazi.

According to one former member of the family's entourage, Jessica's obsession with her own weight regularly spills over into concerns about her kids' diets. Nannies are expected to adhere to her sometimes peculiar food requests and regularly assume preparation of her myriad "healthy" kiddie meals (spinach brownies, anyone?).

The source claims that brittle Jessica's nutritional concerns are borderline obsessive and that play-date calories are closely monitored as well, both at home and when the kids are away. "I know it sounds annoying," she writes in Deceptively Delicious, "but I send my children on play dates with snacks to share ... it's a matter of self-preservation. Too often my kids come home cranky—either from sugary snacks or no snacks at all." That does sound annoying!

Jessica, who started dating Jerry Seinfeld weeks after returning from her honeymoon with then-husband Eric Nederlander, may have borrowed graciously from the Kaavya Viswanathan playbook, allegedly having ripped off the recipes of a less famous, less hot author, Missy Chase Lapine.

Seinfeld has so far avoided any legal action from Lapine.
