Sometimes I feel like Miranda Hobbes is the Jan Brady of “Sex and the City.” Just look at this just released film still from the upcoming “SATC” movie sequel. Carrie, Charlotte, and Samantha all look perfectly “posed” and fabulous, while Miranda looks like she’s showing off her blowie technique on a microphone. WTF? Anyway, by the looks of this photo, the gals are doing some sort of karaoke. Bachelorette party?
