Sex and the city! Is it or isn't happening?

Sarah  Jessica Parker made everyone curious after posting a photo of her filming in NYC wearing heels and carrying a little brown bag. 

Well. I guess the cat’s out of the (little brown) bag.
As usual, we will keep you posted on every detail as we are able.
I’m under a strict gag order until then.

I guess secret is in that little brown bag. We'll just have to wait and see.
