Kristen Davis and Sarah Jessica Parker reunited last week at the premiere of Kristen’s new documentary, Gardeners Of Eden, and since then rumors have been flying that there’s a third Sex And The City movie in the works.

The old friends appeared together on the red carpet when Sarah Jessica came out to support Kristen in New York. The documentary–about the danger elephants face from poachers after their tusks–is on a subject that is near and dear to Kristen’s heart, and her goal is to help educate the world about the very real possibility that elephants will become extinct in the next decade if poaching doesn’t stop.

As for a third Sex And The City movie, none of the stars have or are allowed to comment, but Sarah Jessica Parker posted a photo to Instagram this week that sent fans into a frenzy. In it, she’s shown looking very Carrie, crossing a city street at a run with a shopping bag. Warner Brothers says the photo is not involved in any way with a new movie, but that hasn’t stopped the web from running wild with speculation.

According to People Magazine, the photo is more than likely related to Parker’s shoe line. However, the actress didn’t do much to slow the rumor mill with her caption:

“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 strict gag order until then. Xx, Sj,” she wrote.
