Sarah Jessica Parker revealed that there is still one more story left to tell for a third "Sex and The City" movie, but she was vague about whether it would ever make it to the big screen.

"We've never really had real conversation about it, other than that I know there is a story. I think it's a really lovely, wonderful story but whether or not we tell it remains to be seen," the actress told an audience gathered in France at the Cannes Lions International Festival of Creativity, the ad world's biggest awards competition and trade show, according to The Daily Mail.

Parker, 49, is best known for her role as Carrie in the iconic HBO comedy series and the two big-screen adaptations it inspired. Her comments were recently echoed by Michael Patrick King, who wrote and directed the two films and oversaw the series.

"Sarah Jessica and I both know what that final chapter is," King told Entertainment Weekly in February. "That doesn't mean it will or should be told, but I do think there's one story left. Whether it ever happens is a whole other situation."

So while fans are left hoping for more Carrie and the gang, Parker is busy working on a new show called "Into the Fire," about a daytime talk show host who quits her job to become a stay-at-home mom and soon finds herself involved in an affair with a dad she meets at her children's school.

"Really, it's a portrait of that particular decade of her life that many women are experiencing; you've made some choices and maybe you've discovered that they're not the right choices and you might even have some regrets," Parker told the crowd at the festival in Cannes, according to the Mail. "You're conflicted about love and want very much to be fulfilled but also feel a real connection, and you have a yearning to be a great mother and wife and what we've discovered researching this project is that women are having affairs in their forties."

Meanwhile, Parker, who is about to enter her fifth decade, maintains her trim physique working out with a personal trainer, but the mother of three claims to be no superwoman.

"I work out for a sum total of 22 minutes," she said, "because that's all I can bear."
