Robert Pattinson & Kristen Stewart to star in ‘Fifty Shades of Gray’?

The "Robsten" duo is thinking of making another film together but there's a hold up on their decision. While Robert Pattinson has no qualms on baring everything on screen as shown on his latest flick "Bel Ami", his girlfriend, Kristen Stewart is still thinking things through about baring a bit more on screen.

"Twilight Saga: Breaking Dawn" fans already know that they've already managed to make a steamy session on the film but question is, are they ready to make another one for a whole new different movie, "Fifty Shades of Gray"?

Entertainment Weekly caught up with the new face of Balenciaga and asked her thoughts on taking the sultry female lead role in the film to which she has already heard off from her beau, Robert Pattinson.

"It's funny - I heard about it yesterday. Rob [Pattinson] and Wyck [Godrey], our producer, were talking about it. I've heard it's quite sexy, very titillating," said Kristen Stewart and her answer to the question if she's planning to read the story, "Hell, yeah!"

So what is "Fifty Shades of Gray" all about? The story simply started out as a "Twilight" inspired fan fiction but without the glittery vampires. It revolves around the female lead, Anastasia Steel, a 21-year old college student who starts an affair with a wealthy and handsome entrepreneur, Christian Gray - the human version of Edward Cullen.

The book is already a New York Times best seller and has earned positively raving reviews. A few "Twi-hard" moms have dubbed it as 'mommy porn" and a few fans of the "Twilight" series are taking the lead as hyper fans.

Author E.L. James has one vivid imagination with the revamped characters and his steamy scenes described in the book are nothing compared to Bella and Edward's honeymoon phase in the film, "Twilight Saga: Breaking Dawn Part 1."

Though a few may think it's a slightly watered down version of teen driven sex, it's a full on thrived porn fest as a few readers have suggested. So imagine all that sex being hit on in the big screen, which is more of a big deal for Robert Pattinson and Kristen Stewart.

A few big time studios are battling it out for the right to create it namely Warner Bros, Fox 2000, Paramount, Sony Pictures and Universal. Lionsgate has also shown interest on creating the film but no word from the studio frontrunner yet.
