Sarah Jessica Parker sparks "Sex and the City 3" rumors with cryptic Instagram post

Could Sarah Jessica Parker be slipping back into Carrie Bradshaw's stilettos?

On Monday, Parker shared an Instagram photo of herself leaving New York City's Bloomingdale's department store, dressed in a chic white dress and gold heels. "Well. I guess the cat's out of the (little brown) bag," she captioned the snapshot "As usual, we will keep you posted on every detail as we are able. I'm under strict gag order until then."

The coy caption had some fans wondering if Parker was referencing production on a third "Sex and the City" film, but Warner Bros. says that isn't the case. "The post is not in relation to the 'Sex and the City' property," the studio told E! News in a statement on Monday.

What's more likely is that it has something to do with her shoe line, SJP collection. She tagged the brand in that Instagram post, so it's possible the shoes could soon be sold at Bloomingdale's stores (they're currently available to purchase at Nordstrom, Nieman Marcus and Zappos).

This isn't the first time Parker has used her "Sex and the City" status to promote her line of shoes. Last year, she posed with some of her SJP collection heels on Carrie Bradshaw's famous brownstone stoop.
