Actress Sarah Jessica Parker has sparked rumours there are plans for the third instalment of “Sex And The City”.

She posted a cryptic message on social media on photo-sharing website Instagram along with a photograph, which hinted at a third film, reports femalefirst.co.uk.

The image posted by the 50-year-old actress, features her carrying a paper bag from department store Bloomingdales - which is known for being one of her character Carrie Bradshaw's favourite shops.

Alongside that, she wrote: "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."

The mysterious post follows months of speculation that Parker and her co-stars Kristin Davis, Kim Cattrall and Cynthia Nixon, were set to return for a third instalment.

Back in October 2014, both Parker and Davis hinted they could be reprising their roles when they exchanged a series of tweets seeming to be in reference to the movie.

Davis wrote to Sarah: "Miss YOU XOXOXO!!"

Parker then replied: "Me too you? Head the news? X"

Davis added: "You let me know when we can celebrate."
