'Sex and the City 3': Hints That a New Film Is in the Works

— -- Could "Sex and the City 3" be in the works? New photos seem to indicate that it might be!

Sarah Jessica Parker took to Instagram Monday to post a photo of herself outside of Bloomingdale's in New York City, and hinted that she might be working on a new franchise film.

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

Parker, 50, last played Carrie Bradshaw in 2010's "Sex and the City 2." But in recent months, she and her castmates from the HBO series have been dropping hints that a third installment might be in the works.

In February, 2014, Parker told Harper's Bazaar that there had been no concrete discussions about a third film, but that she and producer Michael Patrick King "know what that story would be."

Then, in October, after Kristin Davis, who played Charlotte York in the show, tweeted at Parker, the actress responded by asking Davis whether she'd "heard the news." Maybe now we know what they were talking about?

A rep for Parker did not respond to a request for comment.
