Kristen Stewart On 'Fifty Shades Of Grey': 'You're Basically Just Reading Porn Right Now'

Fun fact: "Fifty Shades of Grey," the adult novel written by E.L. James, started as "Twilight" fan fiction. That makes Anastasia Steele, the naive young protagonist of the "Fifty Shades" trilogy of books, an alternate-reality version of Bella Swan, the naive youngster-turned-vampire in Stephenie Meyer's franchise.

Kristen Stewart plays Bella in the "Twilight" films and has been a popular choice among fans to star Anastasia in the film version of "Fifty Shades of Grey." (Though not all fans: “I think it would be too strange ... It would just be weird," author James was quoted as saying about Stewart and Robert Pattinson potentially collaborating as the "Fifty Shades" leads.) What does she think of the novel?

"I've skimmed parts of it,” Stewart told Backstage in a new cover story. “When I read the first few pages describing her messy hair, I was like, 'This is so strange.' But it's just so raunchy! I mean, obviously, everyone knows that. But when I see people reading it on planes and stuff, I'm genuinely creeped out. Like, you're basically just reading porn right now! Get that blanket off your lap!"

While Stewart isn't completely well-versed in the "Fifty Shades of Grey" phenomenon (though she did read passages from the book for MTV this summer), her co-star and significant other, Robert Pattinson, has been aware of it from the beginning.

"I read a bit of the 'Fifty Shades of Grey' one,” he told MTV News about his favorite "Twilight" fanfic.
