Talk about keeping appearances up. Have you noticed that for the last couple of years, when photographed together she always has a too-bright smile while he looks like he'd rather be getting an unanesthetized root canal?

Take their picture from the Oscars, for example. She's beaming, trying to look besotted with her doormat husband and seemingly very proud of the fact that her bodice is at least three sizes too small for her overly-augmented breasts. (Did she get them redone? She usually doesn't flaunt them like that.) Her husband, on the other hand, is looking at her and down at them like the latest dead thing the cat dragged in.

These two have long been rumored to be on the rocks. Last summer Matthew reportedly picked up a 25-year-old woman in a Manhattan bar and was even spotted headed to her place with wine and flowers. The couple chose to keep a united front and took off for the Hamptons until it all blew over. Will they split? Sources say that Sarah Jessica is too cheap to divorce him; New York is a community property state and she'd have to give him half of her Sex and the City money. And of course there's their son, 5-year-old James to consider. Apparently they're willing to put up with each other's peccadilloes to keep the peace.
