It’s Friday, so Grub Street feels a little less guilty writing about Kim Kardashian and her wedding cake, even though it’s quite possibly the least important thing in the world. Anyway, there are two things to know: First, that the cake is costing her TV network family (whoever) $20,000. And second, that it’s from the downright delicious Hansen’s, where all the celebs get their empty calories. The wedding, in all its Vera Wang camera-friendliness, is this weekend in Montecito, with the festivities kicking off last night at L.A.’s Scarpetta. We can’t speak to her husband choice (as we don’t know his name), but on the food front … you go, sister. [Page Six/NYP]
