It could have been so awkward: Emma Bunton announcing details of her "no whites" diet (i.e. Atkins without the name of the dead guy attached - no pasta, no bread) while advertising pasta sauces.
Her cultural patron, though, Prego Pasta sauces, is relaxed about the whole affair. After all, it's not like they make pasta, why should they worry?
When life hands them lemons, they'd probably just invent a lemon-based pizza topping. We're not sure we quite can believe someone saying "I'm on a diet, so can't have this sauce on pasta, pass me that meatball sandwich instead..." is a scenario that would ever happen, though. They could have suggested that she slathers herself in the sauce and invites her partner to make like he's pecorino. It might not have sold many jars of mechanical pasta sauce, but it would at least have been more plausible.
