According to a source wittering to Look Magazine, Sarah Jessica Parker's pulled a Miranda by moving to a roomy pad in Brooklyn:

"Sarah clearly loves Manhattan but she has three children now. It might be better for them to grow up somewhere calmer. But Matthew loves their townhouse in Manhattan because it's close to his work on Broadway. It would be a surprising decision to make so soon after the arrival of their twins. Having the babies born healthy and happy was a dream come true, so it's strange that they might have to spend some time apart at this stage."

So, it looks like paying a surrogate to have duel band aid babies didn't quite have the desired bonding effect. Well, it was worth a try, wasn't it? I mean, screw the consequences and the fractured lives, WHEEEEEEEEEEEEEE!
