For the famous "Twilight" couple, the saying "the couple that writes together stays together" is the perfect sentiment.

Robert Pattinson and Kristen Stewart are proving they don't only hit off on and off screen but in writing as well. News is that the famous "Robsten" duo is working together on a script. The big question is: What will it be about?

"Twilight Saga: Breaking Dawn Part 2" is set for a November release, which pretty much means the end of the film franchise. The author of the best-selling novels, Stephanie Meyer, did say herself that there won't be any more books to follow.

"Twi"-hard fans may find this depressing but some who have developed an addiction for the main leads, Robert Pattinson and Kristen Stewart, this only means better.

Stewart and Pattinson have already moved forward from "Twilight" and both stars have had their own films in the 2012 Cannes Film Festival. While Pattinson is busy sleeping with the girls in "Bel Ami", Kristen is fighting off beasts and punching the daylights out of Chris Hemsworth in "Snow White and the Huntsman".

However having been separated off screen for so long, it looks as if Kristen Stewart is ready to make another film with long time beau, Robert Pattinson.

In a recent interview, Stewart confessed to be "dying" to make another film even if it would be the highly-acclaimed BDSM erotica novel, "Fifty Shades of Grey".

"I'm dying to make another movie with Rob, I think that we're a good team," shared Kristen in an interview with Celebuzz.

"I think whatever it is needs to be so ridiculously ambitious. So maybe! I just haven't read it, so I don't know what it is, but I would love to work with him again," continued Stewart.

Making movies isn't the only plan the "Robsten" duo are working together on. Robert Pattinson is currently working on a script with his lovely girlfriend, Kristen.

"We're trying to write a script together," shared Robert in an interview with Ciné Télé Revue. "It won't be for now, but we've thought about it for a long time," explained Pattinson.

While Robert and Kristen are keeping their script under wraps, all "Robsten" fans can do is to show support over the couples' films. "Snow White and the Huntsman" is set for a worldwide premiere tomorrow while "On the Road" and "Cosmopolis" has already been aired at the Cannes Film Festival.
