LOS ANGELES — Emma Watson, rumored to be starring in the bondage flick “50 Shades of Grey,” is shutting those rumors down.

The “Harry Potter” star may be breaking with her brainy Hermione Granger image in her upcoming film “The Bling Ring,” which has her involved in some burglary, drinking and hard partying on-screen, but she hasn’t gone that far.

Watson was rumored to be cast in the starring role of Anastasia Steele, an ingenue who enters into a contract with a mysterious young chief executive named Christian Grey to participate in a bondage-filled, dominant-submissive sexual relationship. News broke about the casting when the online collective Anonymous reportedly hacked into German studio Constantin Film’s internal server earlier this month and posted a document that said Watson was attached to the upcoming adaptation of an E.L. James best-selling, ultra-steamy book series.

Despite casting reports and the hacked documents, Watson made it clear that she wasn’t interested in the sexually explicit role.

“Who here actually thinks I would do ‘50 Shades of Grey’ as a movie? Like really. For real. In real life?” Watson tweeted Saturday, adding on Sunday, “Good. That’s sorted then.”

But this isn’t the first time “The Perks of Being a Wallflower” star has been linked with the film. She already shut down rumors over the summer about her involvement in the likely NC-17-rated flick.

“I haven’t read the book, I haven’t read a script, nothing,” the 22-year-old told Entertainment Weekly last summer.
