...is doing herself no favours by admitting to this (quelle horreur!):

"She wore a slim black McQueen sheath, printed with a thin plume of cigarette smoke, to an SATC event in New York. “He’s incredible. I actually had to cut myself out of that dress that night. My husband was out of town, so I was alone when I got home, and I couldn’t unzip it. So,” she says, wincing, “I got out the scissors.”"

Clue: She channels Diana Vreeland in the March issue of Harper's Bazaar.
